Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application] The present invention relates to a coloring agent for cut flowers, fresh flowers, etc., and further relates to a coloring method that maintains the freshness and activation of fresh flowers that have been changed to a desired color tone.

[Conventional technology]

There are known coloring agents and methods for coloring fresh flowers, such as spraying and depping methods using paint as a coloring agent. , they are flammable and toxic, and the resins used are mainly those that have odors themselves, such as acrylic resins, oil-modified alkyd resins, and phenolic resins, and there are disadvantages such as a strange odor remaining in the coloring process or on fresh flowers after coloring. . Furthermore, depending on the type of solvent used, these solvents can seriously harm fresh flowers, cause cells to die, and even if they can be colored, the freshness of fresh flowers may be impaired, that is, they may quickly wilt.

Furthermore, due to the nature of the resin, the colored film is uniformly applied, which significantly impedes the breathing and transpiration of fresh flowers, causing them to wilt in a short period of time, as well as being sticky due to poor drying and attracting dust due to static electricity. There are various problems such as dirt and dirt adhesion. There is also a method of soaking the cut end of a cut flower in a coloring solution and absorbing it to color it, but this method may cause the leaf veins and petals to be colored in stripes, or the pigment may be deposited on the tip of the flower, resulting in uniform coloration. However, color retention is not stable, which is a problem.

[Problem to be solved by the invention]

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

(1) Problems with the odor of resin coatings (2) Problems with suppressing respiration and transpiration of fresh flowers due to (3) Problems with stickiness and staining of the surface due to (4)
Problem of significant damage to fresh flowers caused by organic solvents (5) Problem of freshness retention (wilting) of fresh flowers after coloring [Means for solving the problem] In order to solve these problems, the present inventor has conducted extensive research. As a result, the present invention was completed.

That is, according to the present invention, a coloring agent for fresh flowers is characterized by containing (a) a water- or alcohol-insoluble microporous substance and Φ) a water- or alcohol-soluble binder, and after coloring fresh flowers with the colorant, The present invention provides a method for coloring fresh flowers, which comprises applying a solution of a living cell activator and/or a carrier for the activator to the fresh flowers.

〔composition〕

The water- or alcohol-insoluble microporous material of the present invention (a
) is an organic or inorganic compound that is slightly soluble or completely insoluble in water or alcohol, and is a fine particle that has dispersibility in these, and forms pores in the film formed by the binder (b).

Specific examples include (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 to black), carbon black, chromium compounds (yellow), ultramarine, molybdenum compounds (red), and other inorganic pigments; azo compounds (azo lake, red), phthalocyanine compounds (blue to green) ), thren compounds (yellow to orange),
Organic pigments such as indigo compounds (blue to reddish-purple); (4) Synthetic resins such as polyurethane, polystyrene, acrylic resin, polyethylene, polyester, epoxy resin, phenol resin, and alkyd resin, or foams thereof.

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

Water- or alcohol-soluble binder (b) is a binder that, when a coloring agent is applied to the petals of fresh flowers, retains the dye and pigment and forms a film by scattering the solvent on the petal surface.
Depending on the ingredients, fine pores can be formed.

Specific examples include (1) natural resins: gelatin, shellac (Gifu Nanauk Co., Ltd., GSL), gum arabic, rosin,
(2) Semi-synthetic resins such as sodium nyalginate and carboxymethyl cellulose; (3) Synthetic resins: natural resin-modified phthalic acid resins, maleic acid resins, phenolic resins, acrylic resins, polyvinyl alcohol, etc. Preferably, natural resin-modified maleic acid resin (Dainippon Ink Chemical Industry ■,
Veracasite J-896), which has as little odor as possible, is selected.

The amount of these added is preferably 5 to 20% by weight in the colorant.
, more preferably 10-15% by weight.

Outside these ranges, there are drawbacks such as insufficient film formation on fresh flowers and premature wilting.

The fresh flowers of the present invention may be any type of fresh flowers, such as cut flowers, flowers, open flowers, etc. Flowers with white petals are particularly preferred for coloring.

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 the above-mentioned inorganic pigments,
In addition to organic pigments, (1) dyes: azo compounds (acidic azo,
Basic azo, red), anthraquinone compounds (red to orange)
, indigo compounds (yellow), phthalocyanine compounds (
(2) Food coloring agents: Yellow No. 4, Red No. 104, phycocyanin, Monascus pigment, etc. It will be done.

The coloring component 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.

As solvent, water or alcohol or a mixture thereof is used. In some cases, it is possible to use water-soluble organic solvents other than alcohol, but in this case there are restrictions such as no odor, a 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 the ability to dissolve and dissolve the live flower cell activator and its carrier, which is another feature of the present invention.
It is important to have the ability to disperse.

Water and/or alcohol are suitable as the solvent, but since water alone has a slow drying rate, it is more preferable to mix it with alcohol. The mixing ratio is alcohol:water=1=9
~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, mixing ratio, degree of polymerization, distribution of degree of polymerization, etc., but generally it is 90 to 50% by weight, preferably 90 to 50% by weight based on the total composition.
It is 80% by weight.

The living cell activator of fresh flowers of the present invention is selected from substances known as herbicides that prevent the aging metabolism of plants and promote cell activation.

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/growth regulator), ,(E)
-1-(P-chlorophenyl)-4,4-dimethyl-
2-(1,2,4-triazol-1-yl)-1-penten-3-ol), balobdrazole (generic name,
Fungicide/growth 1! Conditioner, 1-(P-chlorophenyl)
-4,4-dimethyl-2-(1,2,4-triazol-1-yl)-1-pentan-3-ol), pentane (product name, -ship name Guazatine acetate, fungicide, Dainippon Ink Chemical Industrial products such as 1.1-iminiodi(octamethylene)diguanidinium triacetate).

The amount used is 0.001 to 0.1% by weight, and 0.
If the amount of OO is less than 1% by weight, no effect will be observed;
If the amount exceeds 1% by weight, 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 effect is similar to that of the flower. The mechanism by which this chemical solution prevents fresh flowers from wilting is currently unknown, but it is clear that silver salts,
Its action is different from commercially available cut flower life-extending agents such as Class I and salts, as it has bactericidal, growth regulating, and herbicidal effects, and its mechanism of action is related to the ethylene production mechanism, which is one of the causes of plant aging. It is presumed that there are.

The active agent carrier for fresh flowers is a substance that makes the above-mentioned active cell active substances of fresh flowers act more effectively, such as sugars and surfactants, and by adding these, the effect of preventing wilting can be increased. It is something that can be improved.

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 (product name of Junsei Kagaku Co., Ltd.) (polyoxymethylene surfactant), etc. are effective. The amount added is preferably O, 1 to 3% by weight.

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.

After coloring the petals of fresh flowers with the coloring agent for fresh flowers of the present invention by spraying or the like, or by immersing the petals in a solution of the coloring agent, the fresh flower living cell activator and/or the fresh flower active cell activator carrier Add about 1 colored fresh flower to a solution of
After soaking for ~5 seconds, preferably about 2 seconds to fully infiltrate, shake off the acid solution thoroughly. With this coloring method,
It can promote the respiration and transpiration of fresh flowers, give them activity, and keep them as fresh as or even better than before coloring.

〔effect〕

According to the present invention, even if fresh flowers are arbitrarily colored, there is no odor.
The method of the present invention can 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. By applying a chemical solution consisting of an active cell activator and/or a carrier for the activator to fresh flowers, the freshness of fresh flowers can be maintained for a long period of time without causing them to wilt.

Examples of the present invention will be described below, but the present invention is not limited to these examples.
” is based on weight unless otherwise specified.
