Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel aroma transfer printing process with great industrial applicability.

Conventionally, the method of using aromatic substances in textile printing to impart fragrance to cloth or film-like materials has been to mix fragrances into a printing paste consisting of an adhesive such as natural or synthetic resin, and in some cases add dyes such as pigments. A simple method belonging to the so-called pigment-resin printing method has been attempted, in which the fragrant substances are simply mixed into the resin film. Because the perfume substances are always exposed, whether absorbed or in a mixed state, Insunji emits a strong aroma;
Volatilization losses during and after the printing process were significant.

That is, in general, in pigment resin printing, approximately 140 to 2
Dry heat treatment for 3 to 10 minutes at a high temperature of 0 ps or 1
Steaming is performed at 00 to 140° C. under normal pressure or high pressure for 10 to 48 minutes. In addition, in some cases, washing with water,
Soaping, reduction soaping, acid washing, resin processing, etc. are added. After going through such a harsh printing process, and also through the product storage period, it is washed at least several times at the consumption stage.
It has been impossible to obtain a highly durable aromatic textile that can withstand drying and the like using the conventional aromatic textile printing method described above. Next, fragrances are often made up of a mixture of several dozen types of toning agents, modulating agents, conditioning agents, and conditioning agents, based on several types of base agents, and it is only through the cooperative effects of these agents that subtle pleasure can be created. It produces a fragrance that lasts.

Therefore, they have no meaning unless they are always present in the same place and at the same time, but it is possible to make these multiple foreign substances coexist in the same place and at the same time to exhibit their performance effectively. This is actually quite difficult. Therefore, it was considered to create a separate printing paste for the purpose of protecting the printing paste containing the aromatic substance, and to sandwich the paste containing the aromatic substance between layers, but the aromatic substance had a low density and
It is similar to the conventional method mentioned above that it is easily distributed over a wide range and evaporates easily, and in addition, the film formed from the upper and lower printing pastes must maintain sufficient thickness, which is necessary for the printing process. Therefore, it has many drawbacks, such as significant hand-strength hardening and two additional printing steps.
In recent years, fragrance substance-containing granules obtained by encapsulating fragrance substances in so-called microcapsules have been blended into printing pastes to protect their odor-emitting properties, and as a result,
It is certainly recognized that printed objects obtained from printing pastes containing the fragrant substance-containing granules are considerably superior in the persistence of their desired fragrances.

However, as is well known, the printing layer of the printing paste in ordinary pigment resin printing needs to be extremely thin;
In this case, if the above aroma substance-containing granules are used, the resin aggregate content must be increased to prevent the granules from being exposed on the surface, or the particle size of the granules must be made extremely fine. There is a need.

However, due to mechanical operation, printing paste penetrates deeply into the material to be printed and forms a film, so an increase in the amount of resin mold causes noticeable hardening of the texture, which is the reason for the decline in product value. Therefore, the particle size of the granules must be limited to 5 mm or less, preferably 0.5 mm to 1 mm. This leads to a decline in sexual performance. Furthermore, since the printing process requires long-term heat treatment, etc., the granules themselves are easily destroyed during the process, resulting in a loss of aroma and often resulting in little encapsulation effect.

Furthermore, since the degree of dependence on the capsule membrane material is extremely large, it is necessary to carefully select it and improve the performance of the membrane, and there are restrictions from this point of view. In summary, it has been impossible to obtain a practical aromatic printed product using conventional methods.

The method of the present invention fundamentally eliminates the drawbacks of the above conventional methods,
The purpose is to provide aromatic printed materials with outstanding effects.

Next, the configuration of the present invention will be explained in detail with reference to the drawings showing one embodiment.

First, the transfer printing sheet used in the present invention, as shown in FIG. It is composed of perfume material particles 3 on which a pattern is printed, and a binder layer 4 made of a pigment, a polymer resin, and the like.

Incidentally, the fragrance substance referred to here is a general term including natural fragrances, essential oils, synthetic fragrances, preservatives, etc., and the fragrance substance particles 3 contain the fragrance substance in a wall-like medium made of a polymer compound. It shall be in a granular form in which it is encapsulated. Examples of the base sheet 1 of the present invention include paper, synthetic paper, cellophane, synthetic resin film, etc. In order to transfer the pattern printed onto the transfer object 5 while seeing through the base sheet 1, It is desirable to use a transparent or translucent sheet, such as parchment paper, glassine paper, etc., being considered suitable.

Release material layer 2 coated on base sheet 1
Examples include natural resins or waxy substances such as rosin and carnauba wax, cellulose derivatives such as ethyl cellulose and acetyl butyryl cellulose, amide resins, olefin resins, vinyl resins, silicone resins, and synthetic resins such as fluorine resins. and their copolymers, mixtures, etc., and these are added to the base sheet 1 in a solution or molten state.
It is formed by coating the entire surface or part of the surface.

Such a release material layer 2 has a binder layer 4 printed thereon.
This prevents the fragrance substance particles 3, pigments, polymer resins, etc. contained therein from entering the inside of the base sheet 1, and also allows the base sheet 1 and the binder layer 4 to be smoothly separated during transfer. Next, the binder layer 4 printed in a pattern on the releasable material layer 2 is composed of perfume material particles which have a polymer resin as an adhesive component and are encapsulated in a wall film made of a pigment and a polymer compound. The material is mainly composed of a three-way mixture of polymer resin, pigment, and fragrance material particles 3 on a releasable material layer 2.
A desired design pattern is printed using a printing ink containing .

The above polymer resins include vinyl chloride resin, ethylene-vinyl acetate copolymer resin, acrylic acid ester resin, styrene-butadiene copolymer resin, chlorosulfonated polyethylene resin, chlorinated polyolefin resin, saturated polyester resin, and urethane resin. , nylon resin, etc.

The film formed from these resins is preferably flexible and has rubber elasticity or similar properties, and has a melting point or softening point of 50 to 200°C, and these resins can be used alone or as a mixture in the printing ink. It is used, and is fixed to the cloth or film-like transfer material 5 in a melted or softened state during transfer, and has a flexible feel without spoiling the texture.
It functions to maintain fastness to rubbing and fastness to washing. In this case, by using a polymer resin that has thermal crosslinking performance and allowing a corresponding crosslinking catalyst to exist in an appropriate form, the polymer resin will generate crosslinks during thermal transfer, resulting in printing fabrics, etc. Improving wet rubbing fastness and washing fastness, as well as dry cleaning fastness and hand washing fastness, and deformation of designs by hot iron pressing during the consumption stage of transfer printed products. This is effective because it is possible to prevent migration to non-printed areas, and furthermore, the perfume substance particles 3 are more strongly held on the transfer object 5. Here, the polymer resin having thermal crosslinking properties includes, for example, methylol acrylamide resin, alkoxymethyl acrylamide copolymer resin, glycidyl methacrylate copolymer resin, etc., and the corresponding crosslinking catalysts include: For the former two, for example, ammonium chloride, magnesium chloride, zinc nitrate, alkanolamine hydrochloride, baratluene sulfonic acid, maleic anhydride, salicylic acid, etc. are used, and for the latter, for example, dicyandiamide, phthalic anhydride, aromatic anhydride, etc. are used. Group diamines, imidazoles, hydrazides, polyhydric phenols, etc. are used.

Note that it is preferable for the crosslinking catalyst to be present in the perfume material particles 3 for storage purposes. As the pigment used in the patterned binder layer 4, water-impregnable pigments are most suitable.
For example, inorganic pigments such as iron oxide, ultramarine blue, titanium yellow, molybdenum red, carbon black, zinc oxide, titanium white, etc., insoluble azo, anthraquinone, phthalocyanine, quinacridone, isohindrenine, quinophthalone, dioxazine, and thioindigo. Examples of dyes include organic pigments such as aluminum powder, copper alloy powder, metal powder such as gold powder or metallized powder, and dye-colored substances such as crab-light pigments and lake pigments.On the other hand, dyes include disperse dyes, oil-soluble Examples include dyes, architectural dyes, and some basic dyes, which can be used alone or in combination to express colors or patterns.

In addition to the above-mentioned substances, the components constituting the binder layer 4 include an organic solvent, water in some cases, and, if necessary, a thermosetting resin, a plasticizer, a surfactant, a lubricant, a stabilizer,
Addition of viscosity modifiers, ultraviolet absorbers, extender pigments, oils and fats, etc. does not depart from the gist of the present invention.

The main constituents of the binder layer 4 are particles of a fragrance substance encapsulated in a wall film made of a polymer compound as described above, and the purpose of the particle formation is as follows. Although most of the fragrance substances are liquids, they can be made into solids to facilitate fixation.

'o) Each component of the perfume substance is retained in the same location and at the same time.

1. Prevents the aroma components from being altered or decomposed by various solvents and chemicals in the printing ink forming the binder layer 4.

o Fragrance substances are retained in high concentration and in a narrow surface area, preventing aroma loss during transfer operations.

[Dialogue] By selecting the particle wall material, the fragrance intensity and persistence of the product can be controlled arbitrarily, making it suitable for a wide range of applications.

Further, the fragrance substance particles 3 used in the present invention are required to have the following performance.

(a) In terms of printability, the particles should be close to uniform particle size.

{b' The particles do not dissolve in the components of the printing ink, especially the solvents, and the particles are stably scattered among each other. 'c} Do not destroy particles during printing operations, and do not destroy them by touching them with your fingers on transfer printed materials to expose the contents.

'd} The fragrance substance does not permeate through the particle wall film or gradually evaporate from the micropores.

The perfume substance particles 3 in the present invention are manufactured by so-called microencapsulation technology such as interfacial polymerization method, phase separation method, orifice method, submerged drying method, etc., taking into consideration various conditions based on the above objectives and performance. However, in addition, it is also important to be able to stably contain a perfume substance at a high concentration in the particle weight, and to be able to produce particles of any desired particle size.

Polymer compounds used in these granulation techniques and capable of forming wall films include sodium alginate, methyl cellulose,
Natural thickeners such as carboxymethyl cellulose, guar gum, agar, gelatin, gum arabic, etc., synthetic thickeners such as polyvinyl methyl ether, polyvinyl alcohol, polyacrylic acid copolymers, maleic anhydride copolymers, etc. , natural product resins such as dammar, rosin, nitrocellulose, ethylcellulose, thermosetting resins such as phenolic resins, xylene resins, urea resins, melamine resins, epoxy resins, unsaturated polyester resins, polyolefins, polypynyls, Examples include thermoplastic resins such as polyacrylic, polyamide, polyurethane, and polycarbonate resins, natural rubber, synthetic rubber, and protein resins, which form the wall film either alone or in a mixed state. Further, these are used in the form of monomers or polymers, and are finally subjected to gelation, polymerization, crosslinking, etc. to satisfy the purpose and performance.

Next, the fragrances to be used in the fragrance material particles 3 of the present invention include animal fragrances such as eagle scent and dragon spot fragrance, plant fragrances such as pinene, citronellol, geraniol, linalool, citronellal, eugenol, and menthol, terpinel,
Synthetic terbenes fragrances such as borneol, shochu, and jonon, benzyl alcohol, 8-phenylethyl alcohol, phenyl acetaldehyde, anisaldehyde, heliotropin, ethyluaniline, methyl anthranilate, rosephenone, musk Aromatic and alicyclic compound fragrances such as xylol, musk ketone, diasmone, undecalactone, versalide, etc., anise oil, black letter oil, citronella oil, camphor oil, ylang-ylang oil, geranium oil, J-shaped oil, turpentine oil , essential oils such as rosemary oil and the like.

Also included are retention agents such as ethyl benzoate, ethyl phthalate, iris oil and the like, and modulating agents such as higher aliphatic aldehydes and isoignol. These combinations create aromas of natural flowers such as bell orchid, lavender, violet, rose, diasmine, carnation, lilac, hyacinth, lily, beech, heliotrope, and fruit aromas such as apple, banana, pineapple, cherry, and grape.
Furthermore, the imaginative and fantastic fragrance of Chanel and others can be imparted to transfer-printed materials.

Incidentally, the fragrance substance particles 3 of the present invention contain, in addition to the above-mentioned fragrances, surfactants, oils and fats, polymers, pigments,
Although a crosslinking catalyst and the like may be co-included in some cases, this does not depart from the gist of the present invention. Incidentally, it is obtained by a manufacturing method similar to the phase separation method, which is a known granulation technique, and is made of a polymeric compound that can be incorporated into the binder layer 4 on the transfer printing sheet used in the present invention. An example of an included perfume material particle 3 is given.

8% aqueous solution of polyvinyl alcohol (saponification degree 88%) parts by weight (hereinafter, parts by weight are abbreviated as parts).

0.4 [total 2. The mixture was mixed and differentiated using a colloid mill.

Next, add carboxymethyl luulose 10% aqueous solution 3
When the anchor is added and allowed to stand for 5 minutes, it separates into two phases with a sea-island structure. In these two phases, 1 part of an aqueous solution of industrial tannin (50%)
After stirring for 10 minutes, 2 parts of sand and 8 parts of common salt were gradually added and stirred to solidify the particles in the liquid.
This was placed in a furnace for 9U, and the entire amount, which was thoroughly washed with saline, was poured into a 5% formaldehyde aqueous solution for 20 minutes and stirred for 30 minutes. Next, one drop of industrial hydrochloric acid was gradually poured over the entire surface, and after the completion of the process, the solution was left at a temperature of 25q0 for one hour.
The particle wall film was cured, separated in the oven again, thoroughly washed with water, and dried. The thus obtained red flavor substance particles have a particle size of 0.001
It is similar to a spherical substance with ribs of uniform particle size, and is obtained in a powder form of about 16 parts.

In addition, the content of fragrance components in the particles is 20%, the particle wall film is made of polyvinyl alcohol, a highly acidic vinyl copolymer,
The surface layer is formal crosslinked.

The fragrance material particles 3 enclosed in the wall film made of such a polymer compound, a pigment, and a printing ink mainly composed of a polymer resin are printed using a printing method such as silk screen, intaglio, rotary screen, or flexography. The binder layer 4 is formed by printing colors and patterns on the release material layer 2 applied to the base sheet 1, and then removing unnecessary substances such as solvent by drying. A transfer printing sheet used in the present invention as shown is obtained.

It is considered appropriate for the perfume substance particles 3 to be blended in an amount of about 1 to 1 part of the weight of the printing ink, but this depends on the particle size of the particles, the properties of the wall material, the type and content of the perfume. It is determined by considering the amount, the type and content of the resin component in the printing ink, the printing method, printability, and the desired fragrance persistence, fragrance intensity, and color fastness.

Furthermore, in the printing of the transfer printing sheet used in the present invention, the binder layer 4 may span multiple layers, or auxiliary layers may be provided above and below. You can put it in.

The thus obtained transfer printing sheet is then processed by bringing the binder layer 4 into contact with the surface of a transfer material 5 such as cloth or a film-like material, using an iron or a hot press machine, etc.
For example, heat from loo to 200qo x 3 to 19 seconds.
Pressure is applied, and then the base sheet 1 is peeled off from the transferred material 5 as shown in FIG. 2, thereby obtaining an aromatic printed cloth on which a pattern is formed.

The transfer material 5, which is a cloth or film-like material to which the method of the present invention is applied, is made of natural fibers such as cotton, hemp, silk, and wool, recycled or semi-synthetic fibers such as rayon, cupro, polynosic, and acetate, polyamide, and polyester. Woven fabrics, knitted fabrics, knitted fabrics, mixed fabrics, blended fabrics, etc. made of all fibers, such as synthetic fibers, polyacrylic based, polyurethane based, polyolefin based, polyvinyl based, etc., and glass fiber, as well as any of the above. , those obtained as films, and films of leather, natural rubber, synthetic rubber, etc. Among these, the outstanding feature of the present invention is that it is possible to print freely stretchable knitted fabrics and films. There is one.

Next, the effects of the present invention will be listed.

[11] According to the transfer printing method of the present invention, by an extremely simple operation of short-time heat transfer, it is possible to obtain colors and patterns that emit a remarkable fragrance without impairing the texture of the transferred object, and which also has an odor. It is possible to obtain an aromatic printed material that has excellent durability and good fastness properties such as abrasion resistance, light resistance, hand washing resistance, and dry cleaning resistance.

Legs The perfume substance particles used in the present invention can be safely stored on a transfer printing sheet without containing solvents, and therefore,
The advantage of the various granulation techniques is that a wide range of fairly arbitrary product granules can be used.

■ According to the aroma transfer printing method of the present invention, there is almost no deterioration or loss of aroma during the dyeing process of the blended perfume substance particles and during storage of printed products, and the aroma remains stable for a long period of time even at the consumption stage. can be sustained.

{41 The perfume substance particles used in the present invention can employ a polymer compound forming the wall film regardless of whether it is lipophilic or hydrophilic, but since they are individually scattered, they cannot be mixed arbitrarily. It is possible.

Therefore, the fragrance can be subtly adjusted by the influence of changes in external temperature and humidity, body temperature, perspiration, etc. while the printed article is being worn. Furthermore, by blending two or more types of perfume substance particles with different fragrance persistence, the fragrance can be changed daily or seasonally even though the same printed product is used. '51 When the binder layer on the transfer printing sheet used in the present invention coexists with a polymer resin having thermal crosslinking properties and a crosslinking catalyst, the colors, designs, and fragrance material particles to be thermally transfer printed are strongly crosslinked. achieved.

Therefore, the fastness to washing at high temperatures, hot iron pressing, brushing, etc. can be improved. {6} When the transfer printing sheet according to the present invention is used on cloth, the binder layer moves uniformly to the surface of the transferred object.
stick.

Therefore, unlike ordinary printing pastes, it does not penetrate into the fabric and prevent its structure from deforming and spreading, so it exhibits excellent hiding power and cannot impart clear patterns even on colored fabrics. Moreover, the texture is flexible. In addition, elasticity is further enhanced by the action of the highly elastic polymer resin. {7
} By using the transfer printing sheet according to the present invention,
No matter what shape the object is to be transferred, such as a fabric, a cut object, or a sewn product, aroma transfer printing can be applied relatively easily, for example, at home. Example 1 A mixture of 5 parts of silicone resin, 2 parts of amide wax, and 93 parts of xylene was applied to the entire surface of parchment paper using a roll coater to form a releasable material layer, and then 2 parts of Pendindine Yellow was applied on top of it. , 30% butyl acetate/toluene (1:2) of ethylene-vinyl acetate copolymer resin (composition: 68:32% by weight, melting point: 68oo)
Mixed liquid 3 anchors and butyl acrylate, acrylonitrile, butoxymethyl acrylamide terpolymer (composition of 69.1:23.1:8.neck weight%, melting point 8)
3 parts of a 46% butyl acetate/toluene (1:1) mixture of 0 noon ○), 1 part of Ethocel STD-7 (trade name), 1 part of Sorgen 30 (trade name), 3 parts of methyl lysobutyl ketone. were mixed uniformly, and 6 parts of the apple aroma-containing particles described in the example in the text were blended therein to adjust the printing ink consisting of a yellow pigment interspersed with red aroma substance particles to form a pattern of 20 apple fruit parts in diameter. Printing was performed using a silk screen (100 mesh), and by replacing the dyes phthalocyanine phosphorus and carbon black, two types of similar ink, green and black, which did not contain fragrance particles, were prepared. , In the screen version of the pattern of the knotted part,
I continued printing.

Next, it was air-dried at 25°C to form a binder layer with an apple pattern to obtain a transfer printed sheet. Apply the binder layer side of the transfer printed sheet with a coral pattern obtained in this way to one corner of a white cotton gauze cloth, and heat it with an iron to 180 qo.
, and was heated and pressurized for 5 seconds. In this way, by fixing a binder layer on a white cotton gauze cloth and then peeling off the paper, a three-dimensional light red apple fruit pattern with a hyperopic mixture of dense red flavor particles and yellow pigment is created on the leaves. An aroma transfer-printed cotton gauze product with a flexible texture that clearly appears along with the pattern and emits a characteristic sweet and sour apple aroma from the apple fruit pattern portion was obtained.

The obtained printed fabric has excellent color fastness to rubbing and is thought to be a very fun handkerchief for children.

Incidentally, the aroma degree of the transfer printing sheet and the printing cloth used in this example and the washing fastness of the latter are as shown in Table 1 below.
Sufficient practical value was recognized.

Table 1 (Note) Washing fastness is JIS L-0844, A-
The gutter color was determined according to 2K.

In this case, 5 indicates the highest and 1 indicates the lowest. In addition, the aroma intensity is an approximate value of the aroma intensity based on the odor sense of an expert in perfumery, when untreated cloth is taken as 100 (the same applies hereinafter).

As a comparative example, the same printing ink used in this example was printed on the same white cotton gauze cloth using a normal screen printing method, and then dried and subjected to dry heat for the same period of time. The printed surface was uneven, the pattern outline was unclear, and the overlapping surface of each color ink appeared to be soaked, and furthermore, the ink penetrated into the interior, significantly impairing the texture. In addition, there is a significant drop in washing fastness. However, the aroma level was almost as good as in this example. However, if the heating time for sericulture is reduced to a few minutes, the washing fastness will improve;
The aroma level decreased significantly. On the other hand, when the fragrance substance in this example was blended in the same amount and in a non-particle state into the same ink composition, the fragrance level at the initial stage of printing was extremely high, reaching a numerical value of 200. However, the aroma disappeared while the transfer printing sheet was stored for several days. Example 2 Butyryl acetyl cellulose 4 on polypropylene film laminated paper
1 part, 6 parts of amide wax, methyl ethyl ketone.

A paste containing 9 parts of a mixed solvent of toluene (1:1) was printed using a rotary screen printing plate to form a releasable material layer on an area 2 mm larger than the printed area of the binder layer described later. Next, a butyl acrylate to acrylonitrile binary copolymer (76.3:23% by weight, melting point 78q) was added.

Average particle size that can contain the fragrance substance inside: 0.001
A red printing ink containing rose fragrance particles and a yellow printing ink containing jasmine fragrance particles were prepared by preparing spherical particles of 0.005 to 0.005 ribs and blending 5 parts of each into the above-mentioned colored paste. , a rose flower pattern and a jasmine flower pattern were printed on the above partially printed removable material report using two rotary screen plates that did not overlap at different positions.

In addition, printing ink of four colors of yellow-green, brown, navy blue, and black made with Ike pigment, etc., excluding the fragrance material particles of the printing ink, is used for pattern plates of other leaves, branches, leaf veins, kukuri parts, etc. Print in the same manner, then use the rose flower pattern plate again and apply 20% Hypalon (trade name) on the same rose flower pattern printing surface.
A paste consisting of a mixed solution of xylene and methyl isobutyl ketone (2:1) was printed to cover only the area, and air-dried (3000) to form a binder layer on the sheet to obtain a transfer printed sheet.

The binder layer of the transfer printing sheet consisting of the flower pattern etc. obtained in this way is applied to polyester/cotton (on a gray background).
(50:50%) knit blend fabric and heated and pressurized with a hot press machine for 15,000.1 min.

In this way, the binder layer of the transfer printing sheet is fixed onto the cloth to be dyed with a gray background, and by peeling off the sheet, a clear polyester/cotton with mainly rose and jasmine flower patterns is printed on the gray background dyeing. A knitted print was obtained. The rose flower pattern part of the printed fabric emits a rose fragrance, and the jasmine flower pattern part emits a jasmine fragrance, and the printed fabric emits the scent of both, as well as the three-dimensional effect of the elegant flower pattern, making it look like a real flower garden. It was something unique.

Note that the obtained printed fabric did not lose its soft feel as in Example 1, and was excellent in washing resistance and fragrance persistence.

In addition, since the printed surface freely expands and contracts in line with the elasticity of knit cloth, so-called pewter peeling did not occur. In addition, the transfer printing sheet used had almost no rose scent perceivable, and only had a jasmine scent, but when it was transferred onto cloth, it exhibited the desired rose number. Furthermore, the shelf life of the sheet was also very good as shown in Table 2. Furthermore, the aroma, washing fastness and abrasion fastness of the obtained printed fabric were good as shown in Table 3, and sufficient practical value was recognized. Table 2 Table 3 (Note) Washing fastness is based on JIS-L-0860, chisel-clean method, and rubbing fastness is based on JIS-L-0849.

As a comparative example, when the same printing ink used for the transfer printing sheet was used to color the same cloth using a normal printing method, the print was hard in texture or unclear with poor fastness. It was clearly determined that commercialization would be difficult.

Example 3 Using the transfer printing sheet of Example 1, heat and pressure transfer was performed at 16,000 for 3 seconds on synthetic leather made of vinyl chloride.
Children's shoes and sandals products printed with an apple pattern were obtained.

When these products were exposed to direct sunlight for one month and the reduction in aroma was compared, it was found that the aroma was numerically reduced by approximately 50% compared to those stored in the Okadakasho. Therefore, care must be taken when storing it. However, there was almost no problem in terms of commercial value, and other fastness properties were good.
