Abstract:
A photocurable resin composition comprising:(A) an epoxy compound having two or more alicyclic epoxy groups; (B) a cationic photopolymerization initiator; (C) a polyfunctional monomer having two or more ethylenically unsaturated groups in one molecule; (D) a radical photpolymerization initiator; (E) a polyol having three or more hydroxyl groups in one molecule; and (F) core shell particles having an average particle diameter of 10-700 nm, wherein said core shell particles include (i) a partially crosslinked core selected from the group consisting of polybutadiene, polyisoprene, styrene/butadiene copolymer, styrene/isoprene copolymer, ethylene/propylene copolymer, etbylene/&agr;-olefin copolymer, ethylene/&agr;-olefin/polyene copolymer, acrylic rubber, butadiene/(meth)acrylate copolymer, styrene/butadiene block copolymer, and styrene/isoprene block copolymer; and (ii) a shell selected from the group consisting of methyl methacrylate polymer and methyl methacrylate/glycidyl methacrylate copolymer.
