Title:
PHOTOCURABLE SILICONE RESIN COMPOSITION AND CURED PRODUCT THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/120495
Kind Code:
A1
Abstract:
The present invention provides: a photocurable silicone resin composition that has excellent adhesiveness with respect to a cyclic olefin resin film and a molded body, and which can provide excellent pencil hardness; a cured film; and a laminate thereof. Provided is a photocurable silicone resin composition to be used as a hard coat layer of a cyclic olefin resin film, said photocurable silicone resin composition being characterized by comprising: 100 parts by mass of a silicone resin composition (A) containing, at a mass ratio of 1:99-99:1, a reactive silicone resin (A1) that contains, as the main component, a polyorganosilsesquioxane which has a cage structure in the structural unit thereof and is represented by general formula (1) [RSiO3/2]n (1) (where R is an organic functional group having a (meth)acryloyl group, and n is 8, 10, or 12), and an unsaturated compound (A2) that contains in one molecule thereof at least one unsaturated group which is represented by -R3-CR4=CH2 or -CR4=CH2 (where R3 represents an alkylene group, an alkylidene group, or a -O-C(=O)- group, and R4 represents a hydrogen atom or an alkyl group) and that is capable of radical copolymerization with the silicone resin (A1); and 0.1-20 parts by mass of a photopolymerization initiator (B), wherein the number of moles of acrylic in 100 g of the silicone resin composition (A) is 0.8-1.1, not less than 20 mass% 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).
