Description of the Related Art A wet plating is formed on a concave pattern and / or a character portion of a conventional decorative member such as a watch exterior part, and a dry plating is formed on the other surface, so that the appearance color is multicolored. As a method of manufacturing the product, wet plating such as gold plating is performed on the entire surface of a material such as SUS having a pattern and / or characters formed in a concave shape in advance, and then dry plating is performed, and then the photoresist is immersed in a photoresist and entirely masked. Then, a pattern or a character portion is exposed and removed, and then dry plating other than the masking portion is peeled off and the masking paint is further removed.

According to the method described above, when coating the photoresist on the entire surface in advance, it is impossible to prevent the liquid pool due to the complicated shape, and the thickness of the film varies, so that it is necessary to use a positioning jig for exposure. Difficult to set. In addition, since the resist film is likely to generate pinholes and the pinhole portions are etched, the pinholes need to be corrected, and the working efficiency is poor. In addition, there is a problem that the thin portion of the resist floats or peels off in the etching step, resulting in poor appearance.

た。In the above method, the temperature of the substrate surface rises due to the influence of radiant heat due to the dissolution of the evaporated metal during the ion plating process, so that the gas contained in the masking and the decomposition gas of the masking adversely affect the formation of the ion plating film. Interference color or uneven color of the coating, or discharge or poor adhesion occurs. Further, chipping and peeling of the outer periphery of the masking were apt to occur, and the intended appearance was easily damaged. For this reason, the yield rate was remarkably low, the mass productivity was poor, and the cost was increased.

プになる欠点があった。Further, in the methods (1) to (5), etching of a concave pattern or character is generally performed, but a masking step for etching and a masking step for two-coloring of the concave portion and the other portion are required. Therefore, there were many defects such as positional deviation, and the defect rate was extremely low. Furthermore, since wet plating is also applied to portions other than concave patterns or characters which are unnecessary in appearance, when noble metals such as gold and platinum are used, there is a disadvantage that the cost is increased.

キは不可欠となる。Next, as the material of the decorative member of the present invention, basically any material can be used as long as it can withstand the temperature during the processing by the dry film forming method. For example, ceramic,
Carbide Ni-based alloys, Co-based alloys, stainless steels, copper alloys, zinc, zinc alloys, plastics and the like can be applied. Generally, hard coatings obtained by a dry film formation method have relatively pinholes interposed therebetween, and therefore, it is necessary to satisfy corrosion resistance quality before coating the hard coating. Substrates such as ceramics, hard Ni-based alloys, Co-based alloys, and stainless steels themselves have good corrosion resistance, and therefore do not basically require base plating, but stainless steel substrates with many free-cutting components such as S (sulfur) Since the corrosion resistance is slightly inferior, it is necessary to secure the corrosion resistance of the substrate by using a single layer or several types of Pd, Pd alloy, or Rh layer as the underlayer. When a copper alloy, zinc, zinc alloy is used as a substrate, Cu, Cu alloy, Ni, Ni alloy are plated or laminated as a single layer or plated, and then Pd, Pd alloy, Rh or the like is plated as a single layer or laminated. It is necessary to ensure corrosion resistance. In particular, for copper alloy, zinc and zinc alloy substrates, the above-mentioned undercoat plating is applied before the dry film formation process to prevent the substrate material from being directly exposed to the high temperature and high vacuum atmosphere during the dry film formation process. It is possible to prevent the temperature inside the substrate material from rising, and to prevent the occurrence of blisters due to the dezincing phenomenon. When plastic is used for the substrate, Ni or the like is generally treated by electroless plating prior to the step of performing the same plating as the undercoat plating on the copper alloy, zinc, and zinc alloy substrates described above. Since the plastic substrate has a low melting point and is an organic substance, gas is easily blown out due to a rise in temperature during the dry film forming process, and poor adhesion to the colored film by the dry film forming method tends to occur frequently. The above-mentioned undercoat plating is indispensable for preventing poor adhesion.

の高耐食性の湿式メッキが好ましい。Next, a method for manufacturing the decorative member of the present invention will be described. By coating the hard colored film as a first layer and a second layer on the material by a dry film forming method, the entire surface of the member is masked with the hard film, so that the surface of the component is burned in the next laser processing step. Adhesion and scratches can be prevented. In the wet plating film coating step after laser processing, the concave pattern or character portion by laser processing is generally performed because the base or base wet plating layer is exposed. Similarly, a film with good adhesion can be formed. However, the wet plating on the dry film other than the concave portion has extremely poor adhesion due to the inertness of the dry film. In addition, considering the variation in the depth during laser processing, when the material is a low melting point alloy such as a Cu alloy, it is necessary to control the laser processing depth to be equal to or less than the thickness of the underlying plating. is there. Further, the final wet plating of the concave portion is made of Au, Au.
High corrosion-resistant wet plating of an alloy, Pd, Pd alloy, Rh, Ru, Pt, Pt alloy or the like is preferable.

あるが５μｍまでひろげても問題ない。Next, a colored film formed by a dry film forming method having different components is laminated on the first layer and the second layer. Generally, a film formed by the dry film forming method has many pinholes. The second layer coating is peeled off through the wet plating and the pinholes of the second layer coating, which are weakly adherent, and at the same time, the wet plating coating other than the concave portions is lifted up and easily peeled off. The thickness of the colored film formed by the dry film forming method is optimally from 0.2 μm to 1.5 μm in view of productivity and adhesion, but there is no problem even if the thickness is spread to 5 μm.

A blue TiO layer 9, which is a compound of Ti and O, was coated by 1.0 μm by the same ion plating method as described above. Next, as shown in FIG. 2 (c), a stainless steel C, which is a compound of Cr and N, is ion-plated.
The rN layer 10 was covered with 0.5 μm. Next, as shown in FIG. 2D, a concave pattern 11 was formed in a predetermined portion of the watch case to a depth of 2 to 3 μm by laser processing under the same conditions as in Example 1. Therefore, the Ni alloy plating layer 8 is exposed in the laser processing pattern in the concave portion. Next, as shown in FIG. 2E, the Au—Cu alloy plating layer 12 is
μm coated. Next, the watch case in the state shown in FIG. 2E was immersed in an aqueous solution of sodium carbonate, and a DC current of 5 V was applied to the watch case as an anode to remove the CrN layer 10 by etching. At this time, the Au-Cu alloy plating layer 12 on the CrN layer 10 is lifted up and removed at the same time, and finally, as shown in FIG. 2 (f), a predetermined portion of the brass watch case is formed by the Au-Cu alloy plating layer. A watch case made of brass having a two-color appearance of pink and a blue color of the other part by TiO was obtained. As a result of a quality test similar to that of Example 1, the brass watch case manufactured by this method was sufficiently satisfied with the corrosion resistance, abrasion resistance, and scratch resistance as the watch case.
