<P>PROBLEM TO BE SOLVED: To provide an active energy ray-curable resin composition which does not easily crystallize and whose active energy ray-cured coating film has high curability and characteristics of excellent hardness, impact resistance, and curl resistance. <P>SOLUTION: An allophanate group-containing (meth)acrylate resin compound is obtained by reacting (B) a hydroxy group-containing (meth)acrylate compound with (A) a polyisocyanate composition which is obtained from (a) at least one diisocyanate selected from an aliphatic diisocyanate and an alicyclic diisocyanate, and (b) polyester-based polyol with a number-average molecular weight of 250-2,000 derived from polyol and ε-caprolactone and which does not substantially include an isocyanurate group and contains an allophanate group. <P>COPYRIGHT: (C)2012,JPO&INPIT |
