1. A silicone-based adhesive protective film formed of a composition comprising an alkenyl group-containing organic polysiloxane mixture, an organic polysiloxane resin, a crosslinking agent, and a hydro-silylation catalyst,
wherein the alkenyl group-containing organic polysiloxane mixture comprises a mixture of a component (i) and a component (ii),
component (i) being an organic polysiloxane having at least one silicon-bonded C3 to C10alkenyl group,
component (ii) being an organic polysiloxane having at least one silicon-bonded vinyl group;
the organic polysiloxane resin comprises at least one organic polysiloxane resin comprising an RaRbRcSiO1/2 unit and a SiO4/2 unit; and
Ra, Rb and Rc are each independently a C1 to C6 alkyl group or a C2 to C10 alkenyl group, and
wherein the component (i) is present in an amount of 10 parts by weight to 45 parts by weight and the component (ii) is present in an amount of 55 parts by weight to 90 parts by weight relative to 100 parts by weight of the alkenyl group-containing organic polysiloxane mixture.
