Description

The present invention relates to a method for decorating molded articles of different materials, and more specifically, for mobile phones, digital cameras, AV equipment, electronic parts, vehicle interiors, vehicle exterior parts, personal computers, PDA related parts, etc. Forming a metal film, metal oxide film, or oxide compound film that is hard and very thin and inferior in wear resistance on the hard and soft parts of a molded product of different materials made by integrally molding the hard and soft materials used. It is about the method of decorating.

  In general, a multi-color multilayer film in which metals, metal oxides, and oxide compounds are laminated by vapor deposition technology is beautiful because it can be decorated with a rainbow color, etc., but it is made of hard material and soft material. It forms a hard and very thin metal film, metal oxide film or oxide compound film on the surface of one or both of the soft parts such as elastomer resin. In fact, it was not possible to maintain the product and it was not commercialized.

For example, the key top 1 made of a hard transparent resin, the key peripheral buffer part (skirt part) 3 made of a TPE member, and the base part 2 are temporarily formed by insert two-color molding. After obtaining this shape, the surface is coated with (1) a white-toned primer, (2) a translucent silver metallic paint, and (3) a special UV curable paint. Between (2) and (3), a metal vapor-deposited layer is provided on the transparent substrate sheet as one that performs pad printing of letters and numbers on the top surface of the key top (see Patent Document 1) or a metal vapor-deposited layer. A portion not covered with the decorative layer by providing a decorative layer having an in-mirror display pattern between the transparent base sheet and the metal vapor deposition layer is used as a mirror region for self-photographing, and The visible light transmittance of the structure on the transparent substrate sheet side from the metal vapor deposition layer is 85 to 100% in the portion where the decorative layer is not provided (see Patent Document 2).

  However, as a material to be coated on the elastomer resin, the key top 1 made of a hard transparent resin, the key peripheral buffer portion (skirt portion) 3 made of a TPE member, and the base portion 2 once obtained this shape by insert two-color molding. After that, the surface is coated with (1) a white tone primer, (2) a translucent silver metallic paint, and (3) a special UV curable paint. Between (2) and (3), if the pad printing of letters and numbers is performed on the top surface of the key top, UV coating is applied to the upper layer of the metal deposition layer on which the metal is deposited on the TPE member fabric. However, even if it is covered with UV coating or a hard and extremely thin metal vapor deposition layer is formed on the fabric of a soft TPE member, problems of peeling and cracking remain over time.

  Furthermore, by providing a metal vapor deposition layer, a metal vapor deposition layer is provided on the transparent substrate sheet, and a decorative layer having a mirror display pattern is provided between the transparent substrate sheet and the metal vapor deposition layer. The portion not covered with the decorative layer is used as a mirror surface region for self-photographing, and the visible light transmittance of the configuration on the transparent substrate sheet side from the metal vapor deposition layer is 85 to 85 in the portion where the decorative layer is not provided. Although 100% is disclosed, the transparent substrate sheet is not an elastomer resin.
