Abstract
Provided is an organopolysiloxane compound serving as a raw material of an organopolysiloxane pressure-sensitive adhesive which has necessary and sufficient pressure-sensitive adhesive strength in a step such as temporary fixing or the like and can be easily peeled off from a substrate in a subsequent step; an organopolysiloxane pressure-sensitive adhesive composition containing the same; and a method for using the same. A chain co-modified organopolysiloxane containing a silicon-bonded functional group (R) that contains a specific (meth)acrylic group and at least one aliphatic unsaturated carbon-carbon bond (R) (but excluding the functional group serving as Rabove); a curable organopolysiloxane composition containing the same, further containing a crosslinking agent, a hydrosilylation reaction catalyst, and a photo-radical polymerization initiator, and having both heat curability and photo-curability.
