[0002]

2. Description of the Related Art Conventionally, there are various methods for patterning furnishings, crafts such as interior goods, and lacquerware. For example, (1) after painting the surface of the craft, directly painting with a brush. Or drawing a pattern, (2) patterning by screen printing, (3) further applying paint such as lacquer, (4) patterning the painted surface after the top coating process in the process of painting crafts To form a recess by scraping into a shape, fill the recesses with paints of different colors, repeat this operation, dry, then polish the surface,
(5) Alternatively, after forming a colored layer on the surface, a masking is partially applied, and a non-masking portion is covered with a colored layer different from the colored layer, and then the masking is peeled off to form a multicolor coating. There are various painting methods such as those to be formed.

[0003]

However, since these painting methods often involve a coating process and a drying process of the film, if the color and design become complicated in the painting process, it becomes complicated and the drying process etc. It took a considerable amount of time, and mass production was poor. In particular, mass production is extremely difficult because each step requires sufficient drying. Furthermore, the conventional method cannot draw a color pattern that is three-dimensional and has a unique sharpness and multi-layered coating that the engraving technique has, and further research has been demanded in these respects.

Therefore, the inventors of the present invention have conducted further studies based on the above problems, and as a result, have applied multiple layers of paints of different colors to each other, and after sufficiently drying the obtained layers, it is necessary. The inventors have found that a desired layer color can be revealed by etching to a depth, and a three-dimensional, sharp, and varied pattern can be drawn, and the present invention has been completed here. Therefore, the problem to be solved by the present invention is to provide a method for manufacturing a craft product having different color painting patterns, which can reduce the drying time and can mass-produce three-dimensional and sharp painting patterns.

[0005]

The above-mentioned problems to be solved by the present invention are achieved by the following inventions. (1) After sequentially coating different colors of paint on the surface of the base material for crafts and drying it to form a heavy coating layer, mask the area other than the etching-required area on the heavy coating layer. To expose a layer of a desired color by performing etching up to the required depth of the coating layer, and then repeatedly performing masking and etching on the above-mentioned overcoat coating layer or on the etched coating layer of the required depth. A method of manufacturing a craft product having different colored patterns characterized by.

(2) The method for producing a craft product having different color painting patterns as described in the above item 1, wherein the paint is lacquer. (3) The method for producing a craft product having different color patterns according to item 1 or 2, wherein the masking is performed using an adhesive resin film. (4) The method for producing a craft product having different colored patterns according to item 1 or 2, wherein the masking is performed by using a photoengraving method. (5) The method for producing a craft product having different color patterns according to any one of items 1 to 4, wherein the etching is performed by a sand blaster and / or a water jet. (6) Crafts with different color patterns according to any one of the items 1 to 4, wherein the etching is performed by using at least one of a router, a lathe, a chisel, and scoring. Manufacturing method.

The present invention will be described in more detail below. According to the present invention, painting is performed by exposing layers of different colors desired by etching a heavy coating layer obtained by coating different color paints using an etching technique. In addition, the drying time is shortened and the three-dimensional and sharp picture pattern can be mass-produced, and the effect is particularly large when lacquer is used as the paint. Further, the masking can be carried out by using a sticking resin film or a photoengraving method, so that a picture pattern rich in the variation of multi-layer coating can be easily obtained.
Furthermore, since the etching can be performed by a sand blaster or a water jet, mass productivity is particularly good.

As the paint used in the present invention, various natural or synthetic paints, especially colored paints are used, but lacquer paints are preferable. Here, the lacquer paint is usually used for a lacquer ware in this technical field, and various kinds of natural or synthetic lacquer are used. Colored lacquer as a colored paint is a mixture of lacquer and an inorganic pigment, and a commercially available product or a product prepared in a pre-work process is used.
The pigment mixed in the present invention includes vermilion, green,
There are various colors such as yellow, brown, and black, and these are generally known as pigments. Examples of vermilion colors include red iron oxide, red lead, cuprous oxide, and the like, and green colors include
Examples include chrome green, emerald green, chrome oxide, and cobalt green. In addition, examples of yellow include yellow lead, cadmium yellow, barium yellow, and the like, and examples of brown include ambar, Siena, and the like. Examples of black include carbon black, oil smoke, iron black, and the like.

In the present invention, the multi-layer coating layer of different color layers coated on the surface of the craft base may be applied by any method such as brush coating or mechanical coating, and may be coated one layer at a time or in a multi-layer simultaneous coating. Good. As the masking used in the method of the present invention, a method of sticking a film for a normal mold, an image forming method, for example, a photoengraving method can be adopted.

In the method using a film for a mold, it is necessary to adhere a resin film to the pattern forming surface and then peel it off, so an adhesive agent is used, and this adhesive agent directly attaches the resin film to the pattern forming surface. It may be used by sticking, or the back surface of the resin film may be coated with a sticking agent in advance and used. As the resin film, vinyl chloride,
It may be one that is usually used as a film of ethylene resin, propylene resin or the like.

The photoengraving method is generally known. For example, the surface of a photocurable resin coating is irradiated with ultraviolet rays or visible light in a specific pattern or shape and then developed with a developing solution to remove non-irradiated areas such as ultraviolet rays. By doing so, a mask can be formed. Examples of the photocurable resin include urethane or polyester-based photopolymers, photosensitive resins having a cinnamoyl group (for example, polyvinylcinnamic acid), photosensitive resins having an acrylonitrile group, unsaturated polyester-based photosensitive resins, and the like. Various photosensitive resins are used, and the type is not limited.

The etching technique used in the present invention includes:
Examples include sandblasters, water jets, routers, lathes, chisels or scoring, which are well known in the art. In the method of the present invention, first, a plurality of different colored layers are formed by sequentially coating differently colored paints on the surface of the craft substrate. Known methods such as brush coating and spray coating are adopted as the method for applying multiple coatings of various colored paints.However, the application of multiple coatings is performed at a stage where each colored coating layer does not dry well. Alternatively, it may be performed one after another at a stage of being dried to some extent.

Preferably, the first layer is applied and then dried normally, and when the surface is free of stickiness, the second layer is applied and dried. This operation is repeated to form a desired number of layers of different colors to obtain a double coating layer. Then, on the surface of the obtained heavy coating layer, masking is applied to the region other than the etching required portion. For this masking, a masking material having abrasion resistance or polishing property is selected from the coating layer. After masking, the unmasked areas of the top layer are etched using etching techniques to first reveal the desired color of the second layer from the top. Next, in order to etch the third layer from the top, the second layer exposed by the etching is further etched, or a desired region of the exposed second layer is masked and masked. The uncoated second layer is etched to reveal the desired color of the third layer. These work will be further advanced.

Finally, when the masking layer is removed, a desired color of each layer appears in the etched region, and a multicolored and three-dimensional vivid tone pattern is obtained. If masking is not used, router, lathe,
Needless to say, a person skilled in the art of painting with a chisel or scribe will directly perform the painting work.

[0015]

In the present invention, layers of different colors are multi-coated in multiple layers, and each layer is exposed to the required depth to reveal the color of each layer, which is three-dimensional and sharp in engraving. It is possible to draw out a variety of colored painting patterns. Further, when multi-coating in multiple layers, the second layer can be applied while the first layer is in a semi-dried state, so that the time required for drying is shortened even if the color and design become complicated in the painting process. Therefore, mass productivity can be improved.
