Description

  The present invention relates to a method for decorating a resin base material or a metal base material. More specifically, the present invention relates to a method of laminating oxide compounds, metal oxides or metals that are very thin and inferior in wear resistance by a vacuum deposition technique or the like. The present invention relates to a method for decorating a resin base material or a metal base material, which is performed on an operation button, an exterior cover, a lens cover or the like of a mobile device that requires wear resistance.

  In general, multi-color multilayer films in which these oxide compounds or metal oxides or metals are laminated by vapor deposition techniques are beautiful and can be decorated with rainbow colors, etc., but they are very thin and inferior in wear resistance. It is limited and used only in parts that do not require wear resistance, such as mobile phone cases, digital cameras, and digital home appliances that require decorativeness and design.

  Conventionally, many of the multicolor multilayer films have been provided with a water repellent coating. In that case, when the hard coat is formed with a silicon-based resin from the top surface of the water repellent coat, It was spherical and did not adhere to the upper surface, making it impossible to form a hard coat.

For example, this printed metal sheet disclosed above comprises an undercoat coating layer exhibiting dyeing properties with respect to a sublimation dye, acrylic resin 40 to 10% by weight, and polyvinylidene fluoride resin 60 to 90% by weight. A transparent or semi-transparent topcoat layer is formed on the surface of the metal plate, and the subbing property is transmitted through the topcoat layer by superimposing the printing surface of transfer paper containing sublimation dye on the undercoat layer and heat-treating it. The dye has penetrated, and the top coat film layer and / or the undercoat film layer may contain a triazine UV absorber and a benzotriazole UV absorber alone or in combination (see Patent Document 1). And an actinic ray curable layer (A) having a thickness of 50 to 300 μm and a pencil hardness of 3H or more on a polymer resin substrate, and a Taber wear of 1000 cycles with a load of 4.9 N and a thickness of 1 to 20 μm. Polymer resin laminate (see Patent Document 2) in which an increase in haze in the test is 10% or less and a hard coat layer (B) having a pencil hardness of 4H or more is laminated in this order, dye, ultraviolet ray An inorganic vapor-deposited resin film, characterized in that a vapor-deposited thin film of an inorganic oxide is provided on one side of a resin film impregnated with one or more of an absorbent or an anti-fogging agent, and a laminate using the same The thing (refer patent document 3) regarding a material is disclosed.
