放射線硬化性シリコーン組成物及び剥離シート
Document Type and Number:
Japanese Patent JP5786798
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a radiation-curable silicone composition, from which such a silicone cured coating can be formed that can develop a sufficient heavy release effect even when a small amount of a heavy release additive is added, and that can suppress decrease in a release force with lapse of time.SOLUTION: A radiation-curable silicone composition comprises: (A) an epoxy group-containing cation polymerizable organopolysiloxane expressed by formula (1):RRSiO(where Rrepresents an epoxy group-containing organic group); (B) a photoacid generator; and (C) a heavy release additive comprising a condensation product obtained by dehydration condensation of (i) a polydiorganosiloxane having an average polymerization degree of 100 to 3,000 and having a hydroxyl group or a hydrolyzable group and (ii) a polyorganosiloxane resin having a (SiO) unit and a (RSiO) unit (in which the total content of hydroxyl groups and hydrolyzable groups is 2.1 mass% or more and less than 10.0 mass%).
