Abstract
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.
