摘要: Problem: To provide a silicone-based releasable adhesive composition that is capable of easily controlling peeling force layer by the composition, and whereby has excellent attachment characteristics releasability characteristics. A further object to sheet-form substrate sheet have formed curing this composition. Resolution Means: The includes an organopolysiloxane resin-organopolysiloxane condensation reaction product obtained between (a1) 100 weight parts MQ type resin containing hydroxyl groups or alkoxy in range 0.3 2.0 % having M unit Q molar ratio 0.6 1.0, (a2) 20 150 chain-like diorganopolysiloxane average degree polymerization 1,000 at least one group group, wherein preferably certain content.
