<p><P>PROBLEM TO BE SOLVED: To provide a dial plate for a clock rendering a clear color pattern without affecting a power generating function of a solar cell at a low cost. <P>SOLUTION: A receptive layer 23 having the color pattern formed of a sublimation dye on the lower face of a transparent base board 22 and a white translucent reflective layer 32 with a dispersed white pigment 29 are layered together. The receptive layer 23 with a thickness of 5-15μm is formed of a dye prepared by mixing 1-20 pts.wt. of an ultraviolet ray absorbing agent shown by chemical formula 3 with 100 pts.wt. of a transparent acrylic urethane resin binder. <P>COPYRIGHT: (C)2003,JPO</p> |
