A silicone hybrid pressure sensitive adhesive composition that cures to form a silicone hybrid pressure sensitive adhesive contains a polydiorganosiloxane having reactive groups. The reactive groups include a silicon bonded(meth)acryloxyalkyl-functional group in a pendant position and optionally a silicon bonded aliphatically unsaturated hydrocarbon group in a terminal position. The silicone hybrid pressure sensitive adhesive composition can be cured via hydrosilylation reaction on a surface of a substrate to form a protective film. The protective film can be used to protect a passivation layer during a process for fabricating an (opto)electronic device such as a flexible organic light emitting diode display. The protective film can be exposed to radiation to reduce tack and facilitate detaching the protective film from the passivation layer.

A silicone hybrid pressure sensitive adhesive composition that cures to form a silicone hybrid pressure sensitive adhesive contains a polydiorganosiloxane having reactive groups. The reactive groups include a silicon bonded (meth)acryloxyalkyl-functional group in a pendant position and a silicon bonded aliphatically unsaturated hydrocarbon group. An adhesive article, such as a tape, can be formed by coating the silicone hybrid pressure sensitive adhesive composition on a surface of a substrate and curing said composition via hydrosilylation reaction (B-staged cure) to form a silicone hybrid pressure sensitive adhesive layer on the surface. The silicone hybrid pressure sensitive adhesive layer contains (meth)acryloxyalkyl-functional groups, which can further react and crosslink via exposure to UV radiation (C-staged cure).
