Organopolysiloxane composition

Abstract

Abstract PURPOSE: To title composition capable of forming cured films having improved releasability by irradiation with ultraviolet light, comprising a mercapto group- containing organopolysiloxane and a specific benzoin-group-containing organosilicon compound. CONSTITUTION: (A) mercaptoalkyl group-containing organopolysiloxane having two or more mercaptoalkyl groups bonded to the silicon atom in one molecule and a viscosity at 25°C ≤ 10,000 CST is incroporated with (B) a benzoin group-containing organosilicon compound expressed by formula (R 1 is H or 1-4C alkyl group; R 2 is substituted or unsubstituted mono functional hydrocarbon gruop; n is a positive integer), wherein two or more of the proups expressed by R 2 in one molecule are alkenyl groups, in such a ratio that the number of alkenyl groups in the gredient (B) may be 0.5W2.0 per mercaptoalkyl group in the ingredient (A) COPYRIGHT: (C)1979,JPO&Japio
