Abstract
A polydiorganosiloxane having both a silicon bonded aliphatically unsaturated group and a silicon bonded poly(meth)acrylate polymer or copolymer is useful in a polyorganosiloxane hybrid pressure sensitive adhesive composition that cures to form a polyorganosiloxane hybrid pressure sensitive adhesive. The polyorganosiloxane hybrid pressure sensitive adhesive composition can be wet-cast or dry-cast on a substrate and cured to form a polyorganosiloxane hybrid pressure sensitive adhesive article. An adhesive article including the polyorganosiloxane hybrid pressure sensitive adhesive is also disclosed.
