PROBLEM TO BE SOLVED: To improve the adhesion of a releasing agent layer to a substrate while maintaining the good releasability of the releasing agent layer for an adhesive agent layer. SOLUTION: The addition reaction type silicone release agent composition contains an addition reaction type silicone resin, a branched organosiloxane oligomer, a crosslinker and a catalyst. The addition reaction type silicone resin is, for example, a polyorganosiloxane having as functional groups at least two alkenyl groups in one molecule. As the branched organosiloxane oligomer, one having at least two alkenyl groups is used. In the composition the number of the alkenyl groups is 0.02-0.08 (molar ratio) based on the number of the methyl groups contained in the composition. COPYRIGHT: (C)2008,JPO&INPIT |
