Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a coloring agent that colors fresh flowers such as cut flowers, pots, and outdoor flowers to a desired color, and also maintains the freshness and activation of fresh flowers. Regarding the composition.

[Conventional technology]

There are known coloring agents and methods for coloring fresh flowers, such as the spraying method using paint as a coloring agent, the defaping method, etc.; , they are flammable and toxic, and the resins used mainly have odors caused by residual monomers such as acrylic resins, oil-modified alkyd resins, and phenolic resins, additives, and other factors. There are inconveniences such as giving off a strange odor.

Furthermore, depending on the type of solvent used, these may seriously harm fresh flowers, cause cells to die, and even if they are colored, they may impair the freshness of fresh flowers.

Furthermore, due to the nature of the resin, the colored coating is uniformly applied to these flowers, which significantly hinders the breathing and transpiration of fresh flowers, shortening their original freshness retention period.

Furthermore, depending on the drying time of the resin, there are various problems such as troubles due to surface stickiness (due to insufficient drying) and dust and dirt due to static electricity characteristics.

In addition, there is a method of coloring cut flowers by placing the cut flower in a coloring liquid and absorbing the coloring liquid from the cut end to change the color, but this method may cause the leaf veins and petals to be colored in streaks, or the pigment may be deposited on the tips. However, there are problems such as not only is it not possible to achieve uniform coloring, but also the retention of the coloring is not stable and it is not always possible to obtain the desired color.

[Problem to be solved by the invention]

The present invention solves the following problems of the prior art.

(1) Odor problem with resin coatings.

(2) The problem of suppressing the breathing and transpiration effects of fresh flowers using resin coatings.

(3) Problems with stickiness of the surface due to the resin coating and dust adhesion due to static electricity, etc.

(4) The problem of severe damage to fresh flowers caused by organic solvents.

(5) Decreased freshness retention ability of fresh flowers after coloring (wilting)
Problem of.

(6) The problem is that it is difficult to maintain a more natural-looking (and desired) color stably.

[Means to solve problems]

The present inventor has improved the above-mentioned problems of conventional fresh flower coloring agents, and in addition to enjoying flowers with colors that match your preferences for a long period of time,
As a result of intensive research to increase added value as a product,
By using a specific colorant composition, we can compensate for the defects and
Surprisingly, they discovered a coloring agent that can maintain freshness for longer than the lifespan of flowers themselves, and completed the present invention.

That is, the present invention provides a coloring agent for fresh flowers, which is characterized by containing (a) a fresh flower living cell activator and a carrier for the fresh flower activator.

The present invention forms a colored film on the petals of fresh flowers by spraying or by dipping the petals in a solution of a colorant composition and drying them naturally, without interfering with the respiration and transpiration of fresh flowers. This is a coloring agent composition for fresh flowers that has the effect of retaining freshness equal to or better than before coloring.

〔composition〕

The fresh flower living cell activator (a) of the present invention is a chemical substance that has the effect of inhibiting the aging metabolism of plants, promoting cell activation, and maintaining the freshness of fresh flowers for a long time. , substances known as fungicides, growth regulators and herbicides.

Examples of the agents used as living cell activators for fresh flowers in the present invention include P-silane (trade name as a herbicide, sodium N'-methoxycarbonylsulfanilamide), triabentinol (generic name, fungicide and growth regulator). agent, (E
)-1-(P-chlorophenyl)-4,4-dimethyl-
2-(1,2,4-triazol-1-yl)-1-penten-3-ol), balobdrazole (generic name,
Fungicide/growth regulator, 1-(P-chlorophenyl)-4
・4-dimethyl-2-(1,2,4-triazole-1
-yl)-1-penten-3-ol), pentene (trade name, generic name, guazatine acetate, fungicide, Dainippon Ink Chemical Co., Ltd. product, 1,1-iminiodi(octamethylene)diguanidinium triacetate), etc.

The amount used is 0.001 to 0.1% by weight, and 0.001 to 0.1% by weight.
If it is less than 0.001% by weight, no effect will be observed;
If the amount exceeds the weight percent, the chemical toxicity of the substance will be noticeable.

Although there are some differences depending on the type of flower and the type of activator, the mechanism by which this chemical solution prevents fresh flowers from wilting is currently unknown, but it is clear that silver salts, sugars, etc. The effect is different from commercially available cut flower life-extending agents such as salts.
Since it has bactericidal, growth regulating, and herbicidal effects, it is presumed that its mechanism of action is involved in the ethylene production mechanism, which is a contributing factor to plant aging. The active agent carrier for fresh flowers is a substance that makes the living cell active substances of fresh flowers act more effectively, such as class Ii and surfactants, and the addition of these can improve the wilting prevention effect. It is possible to increase the

Group Ii includes glucose, fructose, sucrose, xylose, etc., all of which exhibit similar effects. As the surfactant, a neutral surfactant is suitable, and preferably sugar ester, TWIN (manufactured by Junsei Kagaku Co., Ltd.) (polyoxymethylene surfactant), etc. are effective. The amount added is preferably O2
It is 1 to 3% by weight.

In addition to these, the present invention uses microporous forming substances, binders, coloring components, etc. that are insoluble in water or alcohol.

The microporous material is an organic or inorganic compound that is slightly soluble or completely insoluble in water or alcohol, and is a fine particle that is dispersible in these and forms pores in the binder film. Specific examples of these are (1
) Fillers such as calcium carbonate, magnesium carbonate, silica powder, glass powder, silica powder, alumina, clay, talc, barium sulfate, aluminum hydroxide, cellulose powder; (2) Titanium oxide (white), iron oxide (brown) ~black)
, carbon black, chromium compounds (yellow), ultramarine, molybdenum compounds (red), and other inorganic pigments; (3) azo compounds (azo lake, red), phthalocyanine compounds (blue to
green), thren compounds (yellow to orange), indigo compounds (
(4) organic pigments such as blue to reddish purple); (4) polyurethane, polystyrene, acrylic resin, polyethylene, polyester,
Examples include synthetic resins such as epoxy resins, phenol resins, and alkyd resins, and foams thereof.

The particle size is preferably 1 to 1000 microns,
More preferably, it is 10 to 500 microns.

As the coloring component of the present invention, pigments and/or dyes that are soluble or dispersible in water or alcohol are used. These materials may be selected from organic and inorganic materials that are soluble or dispersible in water or alcohols such as methanol and ethanol, depending on the purpose of coloring. Preferably it is soluble in water or alcohol. Specific examples of these pigments and dyes include Leraderm Lemon Yellow, Leraderm B, in addition to the above-mentioned inorganic pigments and organic pigments.
Bordeaux (product of Orient Chemical Co., Ltd.) (1) Dye: Azo compound (acidic azo, basic azo,
Red) Metal-containing compounds such as anthraquinone compounds (red to orange), indigo compounds (yellow), phthalocyanine compounds (blue to green), cyanogen compounds (blue to red), quinoline compounds (yellow), 2) Food coloring agent: Yellow No. 4, Red No. 1
No. 04, phycocyanin, Monascus pigment and the like.

The amount of the coloring component added is preferably 3 to 20% by weight, more preferably 5 to 10% by weight in the colorant. Outside these ranges, the coloring may not be sufficient or it may be uneconomical.

Within this range, the color tone and density can be adjusted as appropriate depending on the object.

As the binder, one that is soluble in water or alcohol is used.

A water- or alcohol-soluble binder is a binder that holds the dye and pigment when the colorant is applied to the petals of fresh flowers.

Specific examples include (1) natural resins: gelatin, CeraNuri (Gifu Shellac Co., Ltd., GSL), gum arabic, rosin, (2) semi-synthetic resins sodium nyalginate, carboxymethyl cellulose, (3) synthetic resins; natural resins. These include modified phthalic acid resin, maleic acid resin, phenol resin, acrylic resin, and polyvinyl alcohol. Preferably, a natural resin-modified maleic acid resin (Dainippon Ink & Chemicals Co., Ltd., .mu.Fukasite J-896) is selected, and those with as little odor as possible are selected.

The amount of these added is preferably 5 to 20% by weight in the colorant.
, more preferably 10 to 15% by weight. Outside these ranges, there are drawbacks such as insufficient film formation on fresh flowers and premature wilting.

These binders can be used alone or in combination, but their selection is important because their ability to form a microporous film varies depending on their type, mixing ratio, solvent composition, etc. Furthermore, if the binder component in the composition is small, the retention power of dyes and pigments will be reduced, making it difficult to adhere them uniformly. In addition, if the binder component is too large, the viscosity of the component will increase, and in both spraying and depping methods, the film thickness will become extremely thick and the porous feature will be lost, and the coating will be difficult to spray and will have uneven color. It is undesirable that this may occur.

The fresh flowers of the present invention are fresh flowers such as cut flowers, spinholes, open-air flowers, etc., and any type thereof may be used. It is particularly preferable for flowers with white petals to be colored.

As solvent, water or alcohol or a mixture thereof is used. In some cases, water-soluble organic solvents other than alcohol may be used, but in this case there are restrictions such as no odor, boiling point of 100° C. or less, and not killing plants.

The volatilization rate and behavior of the solvent are greatly involved in the formation of a microporous resin film, which is a feature of the present invention, and it has the ability to dissolve and disperse the fresh flower cell activator and its carrier, which is another feature of the present invention. This is very important.

As a solvent, water and/or alcohol are suitable, but since the drying speed is slow when using water alone, it is more preferable to mix it with alcohol.The mixing ratio is alcohol:water-1:9 to 9.
:1. Examples of alcohols that can be used include methyl alcohol, ethyl alcohol, butanol, and isopropyl alcohol. The amount of solvent used varies depending on the type of resin, the mixing ratio, the polymerization degree of the resin, the polymerization degree distribution, etc., but is generally 90 to 50% by weight, preferably 90 to 80% by weight, based on the total composition.

The fresh flower coloring method of the present invention is a method for coloring fresh flowers to make them a versatile product and increasing added value. In addition, the lifespan of the flowers themselves can be extended and their freshness can be maintained.

The coloring agent composition for fresh flowers of the present invention can be applied by coloring the petals of fresh flowers by spraying or the like, or by immersing the petals in a solution of the coloring agent composition for about 1 to 5 seconds, preferably about 2 seconds, and thoroughly applying the coloring composition. After infiltrating, thoroughly shake off the acid solution and color. By using such a coloring method, it is possible to promote the respiration and transpiration of fresh flowers, make them active, and maintain freshness equal to or higher than that before coloring.

[Effect] According to the present invention, even if fresh flowers are arbitrarily colored, there is no odor.
According to the present invention, it is possible to provide a coloring agent that does not inhibit the respiration, transpiration, etc. of fresh flowers, does not cause stickiness or stains on the surface of fresh flowers, and does not cause damage to fresh flowers due to organic solvents. Since a chemical solution consisting of a living cell activator and/or a carrier for the activator can be applied at the same time, the freshness of fresh flowers can be maintained for a long period of time without causing them to wilt.

The present invention will be described below with reference to Examples, but as is clear from the gist of the present invention, it is not limited to the Examples. "Parts" and "%" are based on weight unless otherwise specified.
