Abstract
Silicone elastomeric compositions suitable for ultraviolet ray curing comprising: PA1 (A) 100 parts by weight of a polyorganosiloxane of the general formula: EQU (CH.sub.3).sub.2 R.sup.1 SiO--R.sub.2.sup.2 SiO].sub.n SiR.sup.1 (CH.sub.3).sub.2 (1) PA1 wherein R.sup.1 represents hydrogen or a monovalent radical selected from the group consisting of methyl, vinyl, and hydroxy, R.sup.2 represents hydrogen or a substituted or unsubstituted monovalent hydrocarbon radical, 0.02-49.95% based on the total number of R.sup.1 and R.sup.2 groups are vinyl radicals 0.05-49.98% based on the total number of R.sup.1 and R.sup.2 groups are hydrogen and n represents a number from 10-10,000. PA1 (B) 0.5-10 parts by weight of a polyorganosiloxane having an average formula: ##STR1## wherein R.sup.3 represents a substituted or unsubstituted monovalent hydrocarbon radical other than vinyl, a represents a number of 0.01.ltoreq.a.ltoreq. in an average, and b represents a number of 0.ltoreq.b<3 in an average, and a+b being a number from 1 to 3 inclusive, and PA1 (C) 0.1-10.0 parts by weight a peroxyester of the general formula: ##STR2## wherein R.sup.4 represents a substituted or unsubstituted monovalent al…
