Description

  The present invention relates to a three-dimensional caricature in which a decorative pattern made of metal particles is formed on the surface of a material to be decorated, and a method for producing the same.

  Traditionally, lacquer painting is known to form gorgeous decorative patterns by spreading gold powder, silver powder, etc. from various patterns drawn with lacquer. In addition to the basic flat-painted paintings that are decorated after being overcoated, there are high-priced paintings that make the patterns enliven, and edible maki-e paintings that are performed after finishing the intermediate coating. In any of these lacquer paintings, the glazed gold powder or silver powder is hardened with lacquer, and then polished with a fingertip in the so-called torso process to make the surface smooth and glossy and beautiful decorative patterns Trying to get.

  That is, in the basic flat picture, as shown in FIG. 7, when the metal particles 1 such as gold powder and silver powder constituting the decorative pattern are polished in the torsion process, the gold powder and silver powder are compounded. Because it is sharpened with a scouring powder or scouring powder, it must be relatively flat. On the other hand, a high-quality picture, that is, a high-quality picture using a charcoal powder or the like, can make a more three-dimensional decoration pattern and give a luxurious impression.

  In this way, Takatsuki painting has a good three-dimensional impression, but when actually producing Takatsuki painting, lacquer layers and charcoal powder must be stacked in layers, which is extremely enormous. It takes time and must be very expensive.

  On the other hand, as in Patent Document 1 below, various proposals have been made in the past for easily forming a lacquer by applying a sheet-like lacquer, but it is difficult to obtain a three-dimensional decorative pattern. .

JP 2002-225499 A

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a three-dimensional caricature and a method for producing the same so that a three-dimensional decorative pattern can be easily obtained.

  In order to achieve the above object, the three-dimensional pattern painting and the production method thereof according to the present invention include metal particles constituting a decorative pattern on the surface of a material to be decorated such as wood through an intermediate adhesive layer such as lacquer or adhesive. In this case, a hard metal material such as titanium having at least a hard surface is used as the metal particles.

  According to the solid-like caricature and the production method thereof according to the present invention having such a configuration, since the metal particles sown as a decorative pattern have a hard property such as titanium, the sharpening work in the torsion process Even if the surface is sharpened, the decorative pattern will not wear. Therefore, for example, even in the case of performing a flat lacquer painting process that is relatively easy to produce, a three-dimensional expression corresponding to a high lacquer painting can be easily performed.

  At this time, in the present invention, the intermediate adhesive layer described above may be configured to include a lacquer layer, an adhesive layer, or a paint layer. By doing so, the metal particles can be fixed satisfactorily.

  Moreover, in this invention, an oxide film can be formed on the surface of the metal particle mentioned above, and the thickness of the oxide film can be adjusted suitably. By doing so, the surface of the metal particles can be colored, and a variety of colors can be produced.

  As described above, the three-dimensional caricature and the production method according to the present invention are obtained by joining metal particles made of a hard metal material to a decorative material surface via an intermediate adhesive layer such as lacquer or adhesive as a decorative pattern. This eliminates the wear of the decorative pattern when the sharpening process is applied and makes it possible to easily create a three-dimensional expression equivalent to a high-quality picture. Expression can be realized inexpensively and satisfactorily.

  Hereinafter, an embodiment in which the present invention is applied to a “flat picture” will be described in detail with reference to the drawings.

  First, as shown in FIG. 1, a sketch 12 is drawn on a Japanese paper 11 made of light Mino paper using ink or the like, and the fluff of the Japanese paper 11 is crushed, and then the lacquered coating is applied. The position of the pattern with respect to the decorating material 13 is determined.

  Next, the Japanese paper 11 on which the sketch 12 is drawn is turned upside down and traced along the line of the sketch 12 using baked lacquer or the like. After the excess baked lacquer is blotted with another paper, as shown in FIG. 2, the above-mentioned sketch 12 made of baked lacquer is transferred to the decorating material 13 side using the coating brush 14 or the like. , And let it be a “placement”. The “placement” drawn on the surface of the decorating material 13 is a part of the “intermediate adhesive layer” in the present invention. The sketch 12 is fixed by sprinkling or the like.

  After finishing the “placement” as the “intermediate adhesive layer” as described above, as shown in FIG. 3, the painting lacquer 15 is applied along the outline of the transfer sketch 12 ′. Then, the inner side of the transfer sketch 12 'is filled so as to have a uniform thickness, and this is referred to as "ground drawing". The “ground drawing” made of the picture lacquer 15 also constitutes a part of the “intermediate adhesive layer” in the present invention.

  Then, before the “ground drawing” as the “intermediate adhesive layer” is not dried, for example, the metal particles 17 are sprinkled using the powder cylinder 16 as shown in FIG. 4, thereby forming the “decorative pattern”. To “powdering (powdering)”. As the metal particles 17 accommodated in the powder cylinder 16, a hard metal material having at least a hard surface is used, and more metal particles 17 are put on a portion that needs to be raised to form a solid. Keep it.

  Here, at least one of titanium, magnesium, stainless steel, tungsten, nickel, chromium, or an alloy thereof is employed as the hard metal material constituting the metal particles 17 in the present embodiment described above. In particular, when titanium is used, a suitable texture such as so-called tanned silver is obtained.

  After the metal particles 17 made of such a hard metal material are sown, the decorative pattern 18 formed three-dimensionally is hardened by imprinting on the surface and drying, for example, a mixture of raw net lacquer and turpentine oil. . Then, after drying it, rapeseed oil is added to the shaving powder and kneaded into a paste to perform the torsion process.

  For example, as shown in FIG. 5, the sharpening operation in this body-worn process is performed by applying a compound or scouring powder to a cotton cloth 19 wound around a finger. Since the metal particles thus obtained are hard, such as titanium, the decorative pattern 18 will not wear even if the surface is sharpened by a sharpening operation in the body shaving process, as shown in FIG. Therefore, even in the case of performing a flat-sketched picture process that is relatively easy to produce as in the present embodiment, a three-dimensional expression corresponding to a high-priced picture can be easily performed.

At that time, if an oxide film is formed in a thin film on the surface of the metal particles 17 made of the hard metal material, an interference phenomenon of light refracted in the oxide thin film layer occurs. As a result, the surface of the metal particles 17 can be colored as if it were colored. In particular, the oxide thin film layer (TiO ₂ ) when titanium (Ti) is used as the metal particles 17 is formed as a transparent film having a high refractive index, so that a glossy and vivid color can be obtained. .

  Such an oxide thin film layer on the surface of the metal particles 17 can be formed by a known anodic oxidation method or the like. For example, the oxide thin film layer has good conductivity from the above-described shaved picture by the body-cutting process. An oxide thin film layer is easily formed by applying a solution such as starch and applying an appropriate voltage (for example, 27 V) thereto.

  Further, at that time, if the voltage application time described above is appropriately changed, the thickness of the oxide thin film layer formed on the surface of the metal particles 17 can be appropriately adjusted. If this is the case, it is possible to slightly change the color developed from the surface of the metal particles 17 depending on the change in irradiation light, the type of light source, or the difference in viewing angle. You can also.

  Although the invention made by the present inventor has been specifically described based on the embodiments, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. Needless to say.

  For example, in each of the above-described embodiments, a case where a flat picture is produced is shown. However, the present invention can naturally be applied to a high-quality picture or a researched picture.

  Moreover, as a decorating material to be decorated, a metal material, a plastic material, a glass material, or the like can be used in the same manner as well as wood.

  Furthermore, in the embodiment described above, baked lacquer is used as the intermediate adhesive layer, but paint, cashew, urethane, sealer, charcoal powder, and the like can also be used.

  The present invention can be widely applied to a wide variety of decorating materials and maple paintings.
