<P>PROBLEM TO BE SOLVED: To provide a photocurable resin composition giving a coating film excellent in curability, where the coating film surface after evaporation of solvent becomes smooth and tack-free without attracting litter and dust. <P>SOLUTION: This photocurable resin composition includes an unsaturated urethane compound (A) having 10 or more polymerizable unsaturated bonds in one molecule and a photopolymerization initiator (B), wherein the unsaturated urethane compound (A) is obtained by reacting a hydroxy group-containing alkylene glycol-based compound (d) having two or more hydroxy groups in one molecule with an isocyanate group-containing unsaturated urethane compound (c) obtained by reacting a hydroxy group-containing (meth)acrylate compound (a) having a hydroxy group and one or more polymerizable unsaturated bonds in one molecule with an isocyanurate compound (b) having an isocyanate group. <P>COPYRIGHT: (C)2012,JPO&INPIT |
