Zusammenfassung:The present invention provides a photocurable silicone resin composition, a cured film, and a laminate thereof, where the photocurable silicone resin composition has excellent adhesion to cyclic olefin resin films and molded articles and is capable of imparting excellent pencil hardness. The photocurable silicone composition of the present invention is used as a hard coat layer for a cyclic olefin resin film and contains 100 parts by mass of a silicone resin composition(A) and 0.1 to 20 parts by mass of a photopolymerization initiator; where the number of acrylic moles per 100 g of the silicon resin composition (A) is 0.8 to 1.1, 20% by mass or more of the silicone resin composition (A) is an unsaturated compound containing a hydroxyl group, and a benzophenone-based photopolymerization initiator is used as the photopolymerization initiator (B); the silicone resin composition (A) is prepared by mixing a reactive silicone resin (A1) and an unsaturated compound (A2) at a mass ratio of 1:99 to 99:1, where the rea
