Patent ID: 8835523

Claim:
A silicone rubber composition curable by a radial ray comprising, at least, (A) an organopolysiloxane shown by the following general formula (I), (B) a phenyl ester derivative having only one acryl group, (C) a sensitizer sensitized by a radial ray, and (D) a photosensitive dye having a configuration such that a color tone of the photosensitive dye before irradiation by the radial ray is different than a color tone of the photosensitive dye after irradiation by the radial ray, the color tone of the photosensitive dye after irradiation being irreversible, wherein the radial ray is at an irradiance level of 200 to 800 mJ/cm 2 , and/or for an irradiance time of 2 seconds or less, and wherein: each R 1 , R 2 , and R 3 independently represents a monovalent hydrocarbon group having 1 to 10 carbon atoms; X represents the same or different monovalent organic group having an acryl group or a methacryl group; and a, b, c, and d represent respective numbers satisfying the relationships of 0.1≦a<1.0, 0.1≦b<1.0, 0≦c≦0.8, c+d>0, and a+b+c+d=1.
