<p><P>PROBLEM TO BE SOLVED: To provide a dial for clocks utilizing a condensing plate that is rich in decoration in terms of appearance and has sufficient light resistance when being exposed to ultraviolet rays. <P>SOLUTION: The dial for clocks comprises a dial substrate 11, a light- condensing plate 14 formed on the upper surface of the dial substrate 11, and an ultraviolet ray absorption film 16 formed on the upper surface of the light- condensing plate 14. A light reflection film 12 is formed on the lower surface of the light-condensing plate 14, and the ultraviolet ray absorption film 16 contains an ultraviolet absorbent 10 for indicating a chemical expression 1 by 10 pts.wt. at a binder 100 pts.wt. section of a transparent polyurethane resin, etc. <P>COPYRIGHT: (C)2003,JPO</p> |
