ROLLED RELEASE SHEET AND ADHESIVE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a rolled release sheet capable of ensuring stability of peel force even if the winding pressure changes in the rolled release sheet in which a long release sheet is wound into a roll shape and to provide an adhesive material using the release sheet. SOLUTION: The release sheet package is obtained by winding the long release sheet into the roll shape and the release sheet has a release agent layer on at least one side surface of a release sheet substrate. In the rolled release sheet, the release agent layer is composed of a cured film of an addition reaction solvent-free type release agent composition containing an alkenyl group-containing organopolysiloxane containing 1.0-5.0 mass% of an alkenyl groups and having a s viscosity of 50-300 mPa at 25°C. The adhesive material is obtained by using the release sheet. COPYRIGHT: (C)2009,JPO&INPIT
