Abstract
Provided is a curing reactive organopolysiloxane composition that forms a pressure-sensitive adhesive layer having excellent curing properties, a wide range of designable viscoelastic properties such as storage elastic modulus (G') and the like, and practically sufficient pressure-sensitive adhesive strength and tensile adhesive strength. The organopolysiloxane composition comprises: (A) an organopolysiloxane having an alkenyl group; (B) an organopolysiloxane resin with 9 mol % or less of hydroxyl groups or the like relative to all silicon atoms in a molecule or resin mixture thereof; (C) an organohydrogenpolysiloxane; (D) an organic silicon compound having an alkenyl group; and (E) a hydrosilylation reaction catalyst. A ratio (molar ratio) of the substance amount of SiH groups in component (C) relative to the sum of alkenyl groups in components (A), (B) and (D) is 1.0 or more.
