Abstract
There is disclosed a silicone pressure-sensitive adhesive composition based on a siloxane resin component, a polydiorganosiloxane polymer component having unsaturated groups in its molecule, a silicon hydride-functional crosslinking agent and a hydrosilation catalyst, wherein the crosslinking agent is a reaction product of a cyclic or linear organohydrogenpolysiloxane and an unsaturated organic compound selected from alpha-alkenes having 6 to 28 carbon atoms or aromatic compounds having the formula Ph-R.sup.4, wherein Ph represents a phenyl radical and R.sup.4 is a terminally unsaturated monovalent hydrocarbon group having 2 to 6 carbon atoms.
