Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention manufactures stamps, necklaces, chest decorations, and other ornaments, wall hangings, figurines, and other structures with a three-dimensional color / color pattern displaying characters, figures, symbols, etc. On how to do.

[0002]

2. Description of the Related Art Stamp materials include those made of natural materials such as ivory, buffalo, boxwood, ebony, and quartz, and those made of plastic material. However, these materials are monotonous with the color and pattern of the material itself, and there is no material on which the surface of the material is displayed with characters, figures, symbols and the like.

[0003]

DISCLOSURE OF THE INVENTION The present invention provides a method for easily and economically manufacturing a structure such as a printing material in which characters, figures, symbols and the like are three-dimensionally formed with rich colors.

[0004]

According to the present invention, a protein plastic material such as casein plastic is used, and it is dyed or not dyed, and a display portion of characters, figures, symbols, etc. is left on the surface and is different from the display portion. In order to obtain a three-dimensionally deeply dyed pattern and a display portion that appears to be embossed.

[0005]

EXAMPLES The figures show an example of manufacturing a stamp. The printing material (structure) body (1) is formed of a protein-based plastic material such as casein plastic obtained by curing casein with formalin or the like, soybean protein, plastic obtained by curing zein, or the like. The plastic material is about 10-18 cm
A round bar with a diameter is used, and this is cut into an appropriate length and the head is appropriately rounded.

In FIG. 1, a printing material main body (1) made of milky white casein plastic is provided with a display (2) of characters, figures, symbols and the like (a family crest in the illustrated example).

The display (2) is a silk screen (3) using a cutting technique, a blocking technique, and a photographic technique on a screen made of silk, tetron, nylon or the like.
In the illustrated one, among the photographic techniques (the direct method, the indirect method, the direct method, etc.), a film is attached to the screen, a positive film is baked on the film, and then washed with water, that is, The direct method is used (Fig. 1b).

A silk screen (3) having a die-cut display portion (4) corresponding to the display (2) is applied to the stamp body, and an acrylic emulsion adhesive (woodworking) is applied to the die-display portion (4). Bonding material), natural rubber adhesive, or any other material that will not dissolve even after being soaked in a dyeing solution described below to form a display layer (5) by applying a display material that can be peeled off after dyeing (FIG. 1).
c, d). Note that the above-mentioned display material is preferably one that has a quick-drying property and a certain heat resistance.

Next, the printing material body (1) on which the display layer (5) has been formed is put into a dyeing solution (8) for dyeing (9). As the dye, an acid dye or other dye is used, and the dye is dissolved in hot water or the like and heated to about 60 to 100 ° C. to be used as a dyeing solution. The immersion time depends on the amount of dye (shading), but it is about 5
30 minutes usually 15 minutes (about 1 to 1 liter of hot water dye
(In the case of 3 g).

After dyeing, when the display layer (5) is removed,
The display (2) appears to be raised on the stamp body (Fig. 1e). In this case, the display layer (2) is formed on the upper part of the front surface of the printing material main body (1), but it may be formed on the other surface, for example.

FIG. 2 shows a color pattern (6) in which a coloring agent such as a pigment or a dye is mixed in the printing material body (1), and the method shown in FIG. 1 is applied to the printing body. A display layer (5) is formed by dipping the main body in a dyeing solution, and the portion excluding the display layer is dyed so that the color pattern (6) can be seen through slightly. After dyeing, excluding the display layer, the color pattern (6) can be seen more clearly than the display (2), and the color pattern can be seen through the parts other than the display slightly and has a deep three-dimensional relief as a whole. A pattern is obtained (Fig. 2d). In addition, when the dyeing liquor is thickened, the above-mentioned color pattern becomes almost invisible from the dyed portion.

In FIG. 3, the main body (1) having the above color pattern is provided with a light blur pattern (7) so that the color pattern can be seen through. I am) Next, the display layer (5) is formed on the surface of the main body, and the display layer (5) is dipped in a dyeing solution, and the portion excluding the display layer is darkened (a dark dye is used to make the color pattern (6) almost invisible). Staining (using or prolonging the dipping time). When the display layer is removed after dyeing, the color pattern and the blur pattern (7) can be seen from the display (2). It should be noted that, if the dyeing is thin, the color pattern and the blur pattern can be seen through the dyed portion. This blur pattern can also be used in the case shown in FIG.

In FIG. 4, the blurring pattern is formed by changing the time when the main body (1) is put into and taken out from the dyeing solution and the time of immersion in the dyeing solution is different in the longitudinal direction. The main body can be put in and taken out manually or automatically by using an appropriate device.

[0014]

The present invention is constructed as described above, and it is possible to easily and economically form a display of characters, figures, symbols and the like and a three-dimensional color pattern on the surface of a structure such as a printing material.
