Abstract:
Disclosed is an ultraviolet-curable resin composition containing a polyurethane compound (A), a photopolymerization initiator (B), and an ethylenically unsaturated compound (C) other than the compound (A). The polyurethane compound (A) is obtained by reacting an epoxycarboxylate compound (c), which is obtained by reacting an epoxy compound (a) having two or more epoxy groups in a molecule with a monocarboxylic acid compound (b) having an ethylenically unsaturated group in a molecule, with a diisocyanate compound (d).
