Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an artificial flower containing a discoloring agent that produces or decolors Ni1K in various colors by adding a voice adjustment wave, etc., and a method for changing the color of the artificial flower.

Artificial flowers commonly used in the past have their petals and cords colored or dyed in a specific color, and it is impossible to change the color of the flowers. Therefore, when it becomes necessary to replace artificial flowers with new colors in accordance with the color scheme of the room and personal preferences, it is necessary to deal with all of the old artificial flowers, which is uneconomical and lacks the sense of outsideness and taste.

The present invention provides a color-variable artificial flower that is completely different from conventional artificial flowers and can be colored, changed or faded according to preference with a single artificial flower.

The present invention applies at least one color change agent or color change assistant capable of changing the color by adding the color change agent or color change agent to the petals and/or the color change agent.
Or, it is an artificial flower with variable coloration, characterized by being enclosed in leaves.

The color change agent used in the present invention is a pH indicator or a color change dye. pH indicators can change color or disappear depending on changes in the state area, and the following are typical examples of pH indicators that change color.
H region and acidic and basic colors are shown. Furthermore, the first
Among the pH indicators listed in the table, it is particularly preferable to use those whose color change pH is near neutral (approximately pH 7) in connection with the use of the color change auxiliary agent described below, and those with clear color changes are preferable. .

The above-mentioned color-changing pigments are, for example, natural pigments shown in Table 2 that change color due to pH changes. Color reactions due to iron salts, discoloration due to the presence or absence of copper and magnesium, discoloration due to the presence or absence of methicilyl groups, as well as anthocyanins, betacyanin pigments, carotenoid pigments, chlorophyll pigments, and quinone brown pigments. In addition to onyization, it includes various pigments that can change color by performing specific color-changing treatments depending on each pigment, such as specific reagents, oxidation-reduction, presence or absence of metal ions, etc.

In the present invention, color change refers to color change phenomena including color development and color erasure phenomena.

In order to incorporate the color change agent into the artificial flower, a dilute solution of the color change agent is prepared and the petals or #i leaves are impregnated with this solution.

For example, if the artificial flower is made of water-absorbing material such as cotton or rice paper, a dilute aqueous or alcoholic solution of the color change agent is prepared and directly impregnated into the petals or Fi leaves. In this case, even if the color change agent is used at a low intensity of lff1t, sufficiently vivid coloring is possible. In addition, if the artificial flower is made of a hydrophobic material such as an elastomer, it is desirable to mix a small amount of a color change agent with a hydrophilic support solid, such as cotton or grain flour, and apply this to the surface of the flower or leaf. However, such treatment is not necessarily necessary, especially when an organic solvent such as alcohol is used as the discoloration aid described below. In addition, the petal Klk may be attached so that the color change agent forms a specific pattern, or 2
A wide range of color changes can be obtained by applying more than one type of color change agent.

Next, when the color changing agent used in the present invention is a pH indicator, it is an acid solution, an alkaline solution, or a neutral solution that can adjust the pH. For example, acid solutions include strong acid aqueous solutions such as hydrochloric acid and sulfuric acid, inorganic weak acids such as acetic acid, carbonic acid, and Shellic acid, organic acids such as citric acid and tartaric acid, ammonium sulfate, copper sulfate,
Strong acids such as ammonium chloride and Il! It is an aqueous solution of a base salt, etc., and has a voice in the range of 1 to 7.Alkaline solutions include strong acid groups such as sodium hydroxide and potassium hydroxide, weak bases such as ammonia, sodium carbonate, calcium carbonate,
7 to 14 with an aqueous solution of a weak acid such as calcium carbonate and a strong base.
In addition, in order to prevent deterioration due to neutral clearing, etc., it is preferable to use a neutral solution or a solution of a weak acid or base as the discoloration aid.

When the Km colorant is a color-changing pigment, it is an aqueous solution of an acid, alkali or a salt thereof, water, or an organic solvent such as alcohol that can react with the mosquito pigment. Xll'' Lu JIl- is a 4-Y-year-old girl who is lucky enough to have a t decoration ga outside 1
for example! Gunshi') Aill acid, 11 active ingredients, m
Chemical compounds such as copper and metal ions such as anchors can be used, and dyes can be selected as appropriate. This method is different from the case using the pH indicator in that it is possible to change the color according to preference by changing the type of color-changing agent.

Next, in order to change the color of artificial flowers using the color change agent, spray a specific color change agent solution on the petals of the artificial flower or in the form of a 1[K spray to wet the entire surface of the artificial flower. A portion dissolves in the color change aid solution or reacts with the color change aid solution to change color, color or decolor to a predetermined color. ζIf two or more types of color changing agents are used, the color changes to each color. In addition, when Japanese paper mainly composed of bast fibers is used as the material for artificial flowers, it is possible to form a shading pattern using the bleeding of the discoloration aid solution.

When placing artificial flowers in a vase as shown in Figure 1, the artificial flowers should be made of water-absorbing material such as cotton or Japanese paper, and the petals (
a) ff1 (b) A dilute water droplet of a discoloration aid, such as sodium carbonate, in the vase rises toward the petals and leaves through the capillary tube (3) that branches into the leaf (C) etc. as necessary and into the axillary capillary tube. , combined with the water absorption of these materials, the aqueous solution becomes a petal,
It penetrates the entire leaf and mixes with or reacts with the coloring agent, making coloration and discoloration possible. In this method, the color change aid is constantly supplied, so vivid colors are maintained for a long time, and no discoloration or decoloration occurs due to drying of the color change aid. Also, with this method, discolored PM area #)! 4, number 11 color changing agent, i.e. p
) Various colors of the pH indicator can be obtained by incorporating the I indicator into the petal and changing the vase color change aid, that is, the aqueous solution with different voices.Furthermore, acidic or alkaline components are mixed into the petal along with several types of pH indicators. By absorbing and mixing the discoloration aid from the vase, the petals change continuously from the acidic region to the alkaline region or from the alkaline region to the acidic region in a wide curved region. In addition, various color changes can be obtained over time.

Furthermore, in the present invention, in order to sharpen the color change and prevent fading, polyhydric alcohols such as ethylene glycol, tetrapyrene glycol, polyethylene glycol, glycerin, etc. are added to an aqueous solution with a concentration of about 5 to 60% by weight along with a color change aid. It is preferable to use it as

Up to this point, we have explained the case where a color change agent, for example, an indicator is pre-incorporated into an artificial flower, and a color change aid is added thereto. The same effect can be obtained with the artificial flowers of the present invention.
Moreover, the coloring can be changed to several different colors according to your preference, and furthermore, these several types of colors can be changed continuously, so it is not only surprising but also economical because it can be used for a long time. .

Example 1 Petals of artificial flowers made from Japanese paper Kl) Phenol 7-talene, an H indicator, was soaked in 1 weight of ethanol sm, and then the ethanol was removed by drying. Add 1N of sodium carbonate aqueous solution to this and apply it as a spray to the entire petal, and the petal will turn red.

Example 2゜To each of the five petals of an artificial flower made from Japanese paper! It was impregnated with a 1% by weight acidic ethanol solution of each of the pH indicators Toxilin, Chlorophenol, WJ & Cresol Purple, Bromophenol Red and Fire Salmon. Add 1 ethylene glycol to this KIN sodium carbonate solution.
When a mixed solution containing 0% by weight was sprayed, the initially yellow petals changed color to purple, red, bluish-purple, and red, respectively.

Example 8 A mixture of methyl red, phenol 7-talene, bromothymol blue, and thymol phthalene indicators was dissolved in an ethanol-water mixture adjusted to be slightly acidic, and 5 wt.
Create a solution of Impregnate petals made of Japanese paper with this and carbonate in a wet state) I) Insert into a vase containing a 1N aqueous solution of rum. The IJ cum solution is absorbed and diffused into the petals by capillary action, gradually neutralizing the acidic petals, and as a result, the petals change from acidic to alkaline, and the pH shifts from 8 to 10. Then, a continuous change in color of each of the indicators was observed, from red to orange-red, yellow, and back.
