To obtain an inexpensive photocurable resin composition which forms cured coating films being high in the hardness, high in stain resistance and excellent in adhesion to substrates such as inorganic building material decorative laminated sheets and is inexpensive.

This photocurable resin composition comprises (A) a urethane acrylate compound having an unsaturated double bond to be obtained by reacting (a) an isocyanate compound having two isocyanate groups in the molecule with (b) an isocyanuric acid derivative represented by the formula (wherein R1 is hydrogen atom or methyl group; R2 is hydrogen atom or a 1-5C alkyl group; and (n) is an integer of 1-20), (B) an acrylic copolymer compound to be obtained by copolymerizing an unsaturated compound having one (meth) acrylic group in the molecule, and (C) a photopolymerization initiator.
