发明名称 DIAL FOR TIMEPIECE, AND TIMEPIECE
摘要 PROBLEM TO BE SOLVED: To provide a dial for a timepiece having excellent transparency of an electromagnetic wave (a radio wave or light) and excellent esthetic appearance and durability, and a timepiece equipped with the dial for the timepiece. SOLUTION: This dial 1' for the timepiece has a base material 2, a multilayer film 3 equipped with a plurality of layers (metal oxide layers) constituted mainly of a metal oxide, a polarizer 4 having a function for polarizing entering light, and a diffusion layer 5 constituted of a material including a diffusion agent. The base material is constituted mainly of a plastic material. The multilayer film 3 has a molybdenum oxide layer constituted of the molybdenum oxide and a silicon oxide layer constituted of the silicon oxide as the metal oxide layers, and the molybdenum oxide layer is arranged in contact with both surfaces of the silicon oxide layer. The thickness of the multilayer film 3 is 50-300 nm. COPYRIGHT: (C)2007,JPO&INPIT
