Abstract
Provided are a silicone-based adhesive protection film and an optical member comprising same, the silicone-based adhesive protection film being formed of a composition comprising an alkenyl group-bearing organic polysiloxane mixture, an organic polysiloxane resin, a crosslinker, and a hydrosylication catalyst, wherein the alkenyl group-bearing organic polysiloxane mixture comprises component (i) and component (ii), and the organic polysiloxane resin comprises at least one of organic polysiloxane resins, each bearing a R1R2R3SiO1/2 unit (R1, R2, and R3 are each independently an alkyl group of 1 to 6 carbon atoms or an alkenyl group of 2 to 10 carbon atoms) and a SiO4/2 unit.
