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).

A flexible laminate for which increased flexibility and improved durability can coexist, and a flexible display provided with same, are disclosed. The flexible laminate has at least one unit of a laminated structure in which two hard layers closely adhere to each other with at least one intermediate layer therebetween. When the flexible laminate is bent, neutral planes are formed inside each of the hard layers that closely adhere to each other with the intermediate layer therebetween. The flexible laminate satisfies the following expression: a&#xd7;ln(tan &#x3b4;&#xd7;E/0.01)&#x2265;100. In the expression, a is any value ranging from 200 to 2,000, tan &#x3b4; represents a loss factor for a substance configuring the intermediate layer, and Erepresents an elastic modulus (MPa) of the substance configuring the intermediate layer.
