Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a shaped object formed from a clay-like mixture or a solid material such as wood, fiber, paper, etc., and containing a coloring agent or a coloring aid.
Conventionally, shaped objects used as toys and crafts are hydrated silicates, which are used as toys and crafts. Materials made from clay-like kneaded materials such as clay, paper clay, wax clay, and flour clay. Furthermore, if the material is made of solid materials such as wood, fiber, or paper, but is not colored before being molded into a predetermined shape, the surface may be painted with pigment-containing paint after molding and drying. The top is colored and finished. These colors are fixed by colored pigments and do not change color even after application, so they are unexpected and
Furthermore, since the pigment paste film is thinly applied to the surface, the delicate surface shape of the material is smoothed out, and due to changes in the transparent appearance due to the film, for example, when modeling plants and animals in the natural world, the transparency received from natural creatures can be improved. cannot be expressed.

By utilizing the coloring, decoloring, and discoloration phenomena caused by the coloring agent and coloring auxiliary agent of the present invention, these do not form a film, and the coloring agent or coloring auxiliary agent contained in the shaped object is removed near the surface inside the material. The delicate shape of the surface of the material is maintained because the coloring aid or coloring agent in the permeated liquid or gas acts to develop, change, or erase color. Moreover, since it can be freely colored, changed, and erased, it is surprising and interesting to users. You may even try changing the color of a single flower several times a day. Furthermore, since transparency can be controlled by selecting materials, it is possible to create flowers and creatures that are naturally transparent, or on the other hand, objects that are opaque. Because of these characteristics, the shaped objects obtained using the present invention have a wide variety of shapes and colors, and have a high degree of freedom in adjusting according to the user's requirements.

Furthermore, for example, the color of one flower can be changed many times a day, creating a set of interesting objects.

The coloring agent used in the present invention is a pH indicator or a color-changing dye. Typical examples are shown in Tables 1, 2, and 3. Among the pH indicators shown in Table 1, it is preferable to use those whose color change pH range is near neutral (approximately pH 7) in connection with the use of the coloring aid described below, and those with clear color changes are preferable. The six color-changing elements shown in Table 2 change color due to pH changes, and the flavonoid pigments shown in Table 3 change color depending on the pH change, as well as specific reagents, the presence or absence of redox metal ions, etc. Contains various pigments that can change color when subjected to specific color-changing treatments.

Next, the coloring aid used in the present invention is such that the coloring agent has a pH of
In the case of an indicator, it is an acidic, alkaline, or neutral compound or a solution thereof that can adjust the pH. Examples of acidic compounds include strong acids such as hydrochloric acid and sulfuric acid, inorganic weak acids such as acetic acid, carbonic acid, and schikolic acid, organic acids such as citric acid and tartaric acid, and salts of strong acids and weak bases such as ammonium sulfate, copper sulfate, and ammonium chloride. 'It exhibits a pH in the range of 1 to 7 in aqueous solution. The alkaline compound is sulfur hydroxide,
A strong base such as potassium hydroxide or a salt such as sodium carbonate or potassium carbonate, with an aqueous solution of I) in the range of 7 to 14.
There is no particular restriction on the coloring auxiliary agent as long as it can adjust the pH, but from the viewpoint of the effect on the human body, it is preferable to use one that is close to neutrality. A compound in which the above pH-adjusting compound is mixed with other components. For example, natural fruit juices and seasonings can also be used.

In addition, when the coloring agent is a color-changing dye, it is acidic, alkaline, or a salt thereof, or an organic solvent solution such as water or alcohol that can react with the coloring agent, and when the coloring agent is a flavonoid dye, In addition to the above, reducing agents based on magnesium hydrochloride, metal sulfur such as ferric chloride, and tin can be used. In the case of color-changing dyes, various color changes are possible depending on the type.

When the present invention is applied to a clay set, the clay profiteers include grain flour, hydrated silicate minerals, polymer elastomer,
There are clays made from fine powder of paper, etc., and in order to make the color changes clearer and to prevent fading, polyhydric alcohols such as evapoethylene glycol, propylene glycol, polyethylene glycol, glycerin, etc. are added to either or a mixture of them. It is preferable to use it as an aqueous solution with a concentration of 5 to 50% by weight. Additionally, water, preservatives, anti-drying agents, lubricants, sodium chloride, potassium chloride, etc. can be added.

When using a wooden model, you can use any of cedar, cypress, beech, oak, wood, and others. Similarly, the type of fiber and paper does not matter, but it is preferable that the surface of both fibers and paper is not treated with water repellent treatment.There are two main methods for initially incorporating a coloring agent or coloring aid into a shaped object. There is.

(Capital) Shape after kneading the coloring agent or coloring aid with other ingredients.

(B) After modeling, a solution or gas containing a coloring agent or coloring aid is infiltrated into the surface of the modeled object and dried.

When using a clay set, method (A) or (Bl) can be used. When using a human method, a solution containing a coloring aid or coloring agent is applied or sprayed onto the modeled object. For example, a colorless coloring agent is kneaded and molded into clay, and then a solution containing a coloring auxiliary agent is applied to develop color, and then a solution containing another coloring auxiliary agent is applied. By doing so, the color can be erased or changed.At this time, the coloring agent that is initially included is not limited to a single one.

When the coloring aid is included in the modeled object using method (A), a solution containing the coloring agent is applied afterwards. In this case, each part of the object can be easily colored or changed in various colors. As a solution for mixing this coloring agent and coloring aid,
In addition to water and alcohol, ethylene glycol, propylene glycol, ketones, esters, etc. can be added as necessary. It is also possible to use gaseous vapors such as ammonia and chloride.

When using method (B) for clay sets, apply or spray a coloring aid or a solution containing the coloring agent onto the surface of the pre-shaped clay, and after drying, add the coloring aid or solution containing the coloring aid. Color development by applying or spraying a solution or applying a gas.
Discolors or fades. The composition of the solution and the color development method are the same as in the case of (A).

When using wood, fiber, or paper as a model, you can use the methods (2) and (B) in the same way as with clay, or apply a coloring agent or dye to the material before modeling, especially as in the case of wood. For materials for which it is difficult to knead color aids, the Bl method is used.For fibers and paper, the CB+ method is also preferred.

In addition, when using the method (5) when providing these coloring sets to users, a clay-like kneaded body containing a coloring agent or a coloring aid and a solution containing a coloring aid or a coloring agent are used. can be set. Also, a writing instrument for applying this solution, or a writing instrument pre-soaked with the solution. Alternatively, shaping tools such as press molds having various shapes for shaping the clay-like kneaded material can be attached to this set.

As described above, by using the present invention, for example, it is possible to freely color or change the color of a doll's facial expression, hair color, eye color, clothing, etc., and it is also possible to create a set of flowers that have a transparent appearance that is close to natural. Easy to enjoy. The effects of the present invention are as follows.

(1) You can freely color, change, and erase the color of the model, and the variety of color changes creates a surprising and interesting effect. (2) The delicate surface shape of the material is not lost, allowing you to enjoy the fine design. be able to.

(3) It has a great educational effect, as it can be made to look like a natural creature and can reproduce the color changes of the four seasons.
