Definitions
- the present invention relates to a thermal transfer ink necessary to a thermal transfer printer which is expanding the fields of application thereof because it is inexpensive, generates little noize, and is easy to handle.
- Waxes such as paraffin and carnauba wax are predominantly used as the binders of conventional thermal transfer inks, which have a significantly low melt viscosity.
- a clear print having a gloss peculiar to thermal transfer can be obtained.
- various requirements involving printing on a paper having a less surface smoothness printing giving a fast print, printing at a high speed, and repeated printing.
- the conventional ink constituted of wax alone cannot cope with the requirements. Therefore, investigations on inks comprising a resin as the main component are being made in various fields.
- Known resins include one which promises application to the printing on a paper having a rough surface because of its high cohesive force and high capability of forming film, one which promises application to the printing giving a fast print because of its high strength, one which promises application to the printing with a high transfer sensitivity because of its amorphousness, and one which promises application to the repeated printing because of its strong adhesion.
- a possibility of application of a resin to a thermal transfer has been developed.
- resins have a very high melt viscosity as compared with waxes. This tendency is particularly remarkable when they are formed into an ink. In the thermal transfer system, this melt viscosity is an important factor determining formation of a transferred image, thus directly influencing the quality of a print.
- a resin ink has a low viscosity comparable to that of a wax ink in a heat-molten state, a sufficient contact area is secured, thus achieving printing with a high coverage.
- an ink containing a resin having a melting point suitable for thermal transfer as the main component does not generally have a low viscosity comparable to that of a wax when thermal transfer is carried out.
- the inventors of the present invention have made intensive investigations with a view to solving the above-mentioned problems, and as a result, have found that a thermal transfer ink having excellent performances in printing can be obtained by adding an adequate viscosity depressant according to the purpose to any one of various hot-melt resins which have been incapable of being employed because of their high melting points, thereby adjusting the viscosity.
- a thermal transfer ink having excellent performances in printing can be obtained by adding an adequate viscosity depressant according to the purpose to any one of various hot-melt resins which have been incapable of being employed because of their high melting points, thereby adjusting the viscosity.
- the present invention has been completed.
- a thermal transfer ink of a solution type comprising a resin having a melt viscosity of 10,000 to 1,000,000 cps (as measured at 120°C) as the base binder, characterized by containing 5 to 250 parts by weight, based on 100 parts by weight of the base resin, of at least one viscosity depressant selected from the group consisting of resins, waxes, higher fatty acids, higher alcohols, and synthetic esters for the purpose of lowering the melt viscosity, said viscosity depressant having a melt viscosity of 1 to 600 cps, measured at 120°c, and being insoluble in a solvent to use or so partially soluble in the solvent that more than 1 gram of the viscosity depressant may not be soluble in 100 grams of the solvent at 40°c.
- An ink composition of the invention is useful for the thermal transfer and comprises 100 parts by weight of the above defined high viscosity-having resin and 5 to 250 parts by weight of the above defined viscosity depressant or thinner.
- the ink composition further comprises a solvent and then the insoluble portion of the depressant stands in the form of fine particles in the emulsion or the slurry. It may contain the solvent in a conventional amount and a coloring matter.
- the thermal transfer ink of the present invention is obtained by adding a viscosity depressant such as a low-viscosity resin or a wax to a thermal transfer ink having a relatively high melt viscosity and using a resin as the base binder in order to use the thermal transfer ink by lowering its viscosity.
- a thermal transfer ink obtained by adding a partial insoluble portion of a viscosity depressant such as a wax in the particulate form such as an emulsion, a slurry or a fine powder to a solution type ink.
- the thermal transfer ink of the present invention is applied to a base with a conventional means such as a gravure coater and dried to obtain a thermal transfer ink sheet without the need of paying attention to the compatibility of a high-viscosity resin with a viscosity depressant such as a wax.
- any combination of a high-viscosity base resin and a viscosity depressant such as a wax is possible, and any high-viscosity resin can be used as the thermal transfer ink binder.
- a resin which can be used as the base binder in the present invention has a melt viscosity of 10,000 to 1,000,000 cps., measured at 120°c.
- a resin include polyester, polyamide, acrylic, polystyrene, polystyrene-acrylic, polyvinyl chloride, polyvinyl butyral, epoxy, ethylene-vinyl acetate, polyurethane and polycarbonate resins, and mixtures thereof, said resins having melting points of 60 to 120°C.
- the viscosity depressant having a low viscosity which can be used in the present invention is at least one member selected from the group consisting of resins, waxes, higher fatty acids, higher alcohols, and synthetic esters, which have a melt viscosity of 1 to 600 cps, measured at 120°c, and being insoluble in a solvent to use or so partially soluble in the solvent that more than 1 gram of the viscosity depressant may not be soluble in 100 grams of the solvent at 40°c. More preferred are resins, waxes, higher fatty acids, higher alcohols, and synthetic esters which have a melt viscosity of 1 to 400 cps at 120°C.
- any resin can be used as the low-viscosity resin in the present invention in so far as it has a low viscosity.
- resins include polyethylene, polyester, ketone, ethylene- ⁇ -olefin copolymer ⁇ -olefin-maleic anhydride copolymer resins.
- waxes can be mentioned as the wax that may be used in the present invention.
- the waxes include natural plant waxes such as carnauba wax, candelilla wax, ouricury wax, sugarcane wax, and Japan wax; natural animal waxes such as beeswax, spermaceti, Chinese wax, and wool wax; petroleum waxes such as paraffin wax, microcrystalline wax, oxidized paraffin wax, and oxidized microcrystalline wax; mineral waxes such as montan wax, ozokerite, ceresine, and lignite wax; synthetic waxes such as ketone wax, Fischer-Tropsch wax, castor wax, opal wax, Armor wax, and Acra wax; and modifications thereof.
- Any higher fatty acid which is usually used can be used in the present invention.
- Examples of such a higher fatty acid include palmitic acid, stearic acid, margaric acid, and behenic acid.
- Any higher alcohol can be used in the present invention.
- Examples of such a higher alcohol include palmityl alcohol, stearyl alcohol, behenyl alcohol, margaryl alcohol, myricyl alcohol, and eicosanol.
- Examples of synthetic esters that may be used in the present invention include monoesters synthesized from the above-mentioned higher fatty acid and higher alcohol, diesters synthesized from a bifunctional dicarboxylic acid and the above-mentioned higher alcohol, and diesters synthesized from a bifunctional diol and the above-mentioned higher fatty acid.
- Any solvent which is usually used in an ink or a coating can be used in the present invention.
- a solvent include alcohols such as ethanol and isopropyl alcohol; ketones such as methyl ethyl ketone and methyl isobutyl ketone; aromatic solvents such as toluene and xylene; and water. These solvents may be used in mixture if necessary.
- a thermal transfer ink sheet can be produced from the thermal transfer ink of the present invention by applying at least one layer of the thermal transfer ink of the present invention to a base or a coating layer on a base and drying it.
- a combination of the thermal transfer ink layer with a top coat, a resistance layer for heating by passing electricity therethrough, or an electrically conductive layer may be employed.
- the thermal transfer ink of the present invention is usually applied to a base with a coater or a printer.
- a viscosity depressant added is not soluble in a solvent used at all, the interaction between precipitated particles becomes so strong that the structural viscosity is increased, whereby problems of separation of the ink from the gravure meshes in coating or printing and levelling just after the application are presented. Thus, any clean coating film can hardly be obtained.
- a viscosity depressant to be added is at least partially soluble in a solvent used, so that the structural viscosity can be suppressed. As a result, good applicability or printability is attained.
- a thermal transfer ink 1 of a solvent type comprising a polyester resin having a softening point of 90°C (melt viscosity at 120°C: 23,000 cps) as the main component and having the following composition was prepared:
- a solution of a carnauba wax slurry 1 in toluene was prepared.
- this slurry may be one prepared by completely dissolving carnauba wax in hot toluene and cooling the solution, or a slurry prepared by adding a fine carnauba wax powder and, if necessary, dispersing the mixture.
- the obtained thermal transfer ink sheet was evaluated as regards obtained prints by using a commercially available thermal transfer printer.
- the evaluation results are summarized in Table 1. It can be understood from the results that, with an increase in the amount of the carnauba wax slurry, a visocisty lowering effect was developed, whereby a thermally transferred image having a transfer rate and a resolution comparable to those of a wax ink was obtained while keeping the features of the resin, such as fastness.
- a thermally transferred image was obtained under the same conditions as those of Example 1 by using the ink 1.
- Solution type inks each comprising as the main component a polyamide resin having a softening point of 86°C (melt viscosity at 120°C: 17,500 cps), a polystyrene acrylic resin having a softening point of 102°C (melt viscosity at 120°c: 50,000 cps), or a polystyrene resin having a softening point of 78°C (melt viscosity at 120°c: 11,000 cps) (in a 1/1 solvent mixture of toluene and methyl ethyl ketone) were admixed with 10, 20, 30, 40, and 50%, based on the resin, of a mixed slurry composed of polyethylene wax (melt viscosity at 120°C: 30 cps) and carnauba wax prepared at a ratio of 1:1 in the same manner as that of Example 1 to prepare inks.
- a slurry of paraffin wax having a melting point of 105°C (melt viscosity at 120°C: 23 cps) in toluene was prepared.
- the same polyester resin as that described in Example 1 was admixed with 30%, based on the weight of the resin, of the slurry.
- the evaluation of the obtained prints was made in the same manner as that of Example 1 to obtain results as shown in Table 3.
- a polyamide resin having a softening point of 106°C (melt viscosity at 120°C: 120,000) was emulsified by the ordinary method to prepare an emulsion ink.
- a modified microcrystalline wax having a melting point of 87°C (melt viscosity at 120°C: 4 cps) was emulsified with a common emulsifier to prepare an emulsion. 20%, based on the weight of the resin, of the emulsion was added to the above- mentioned emulsion ink. Evaluation of the obtained prints was made in the same manner as that of Example 1 to obtain results as shown in Table 3.
- Example 2 The same resin ink as that used in Example 1 was admixed with 30%, based on the resin, of a polyester resin having a melting point of 78°C (melt viscosity at 120°C: 2,300 cps) to prepare an ink. Evaluation of the obtained prints was made in the same manner as that of Example 1 to obtain results as shown in Table 3.
