LAMINATE COMPRISING PRESSURE SENSITIVE ADHESIVE AND LINER RELEASABLE FROM PRESSURE SENSITIVE ADHESIVE

摘要

PURPOSE: To satisfactorily separate a silicone pressure sensitive adhesive from a releasable liner by using an adhesive layer comprising a pressure sensitive adhesive layer and a specified curable fluorosilicone compsn. on the surface of the liner. ;CONSTITUTION: This laminate comprises: a pressure sensitive adhesive layer; and a liner provided with a coating releasable from the pressure sensitive adhesive, the coating being formed by coating the surface of the liner with a coating compsn. contg. the following components (A) and (B) and curing the compsn., wherein the liner is separably bonded to at least part of the pressure sensitive adhesive by utilizing the coated surface thereof. The component A is a fluorosilicone polymer represented by formula. The component B is a curing agent comprising a platinum-contg. hydrosilylation catalyst and an organohydrogensilicon crosslinking agent. In the formula, Y represents Me (a methyl group) or A (a ω-alkenyl group); R represents a 4-8C perfluoroalkyl or the like; and x, y, and z are larger than 0 or the like.;COPYRIGHT: (C)1993,JPO
