Abstract:
A radiation-curable silicone rubber composition comprising;(A) an organopolysiloxane represented by the general formula (1): ##STR17## wherein R.sup.1 's are independently a substituted or unsubstituted monovalent hydrocarbon group having 1 to 9 carbon atoms; and X's are independently an organosilicon group represented by the general formula (2): ##STR18## wherein R.sup.2 is a divalent hydrocarbon group having 2 to 4 carbon atoms or an oxygen atom; R.sup.3 is a monovalent organic group having 4 to 25 carbon atoms, having 1 to 3 acryloyl or methacryloyl groups represented by the general formula: ##STR19## wherein R is a hydrogen atom or a methyl group; R.sup.4 is a substituted or unsubstituted monovalent hydrocarbon group having 1 to 9 carbon atoms; R.sup.5 is a monovalent hydrocarbon group having 1 to 18 carbon atoms; n is an integer of 1 to 3, m is an integer of 0 to 2, and 1>n+m>3, provided that R.sup.3 has a plurality of acryloyl or methacryloyl groups when n is 1; L is an integer of 8 to 10,000; and R.sup.3 (inclusive of R), R.sup.4 and R.sup.5 which are each present in plurality may each be same or different;(B) a photosensitizer; and(C) at least one organosilicon compound selected from an alkoxysilane represented by the general formula: Si(OR.sup.6).sub.4 wherein R.sup.6 is an alkoxy-substituted or unsubstituted alkyl group having 1 to 4 carbon atoms;and a partial hydrolysis-condensation product thereof.
