Abstract:
A curable resin composition comprising:(i) 0.5-80 parts by weight of an acrylic polyol resin (A) comprising a hydroxyalkyl(meth)acrylate composition having 0.3 to less than 1.0 mole of polymerized lactone monomer being polymerized by ring-opening with respect to 1 mole of hydroxyalkyl(meth)acrylate, wherein the content of the lactone monomer in the hydroxyalkyl(meth)acrylate composition is 0-10% by weight, and a proportion of monomers having two or more continuous chains (n&gE;2) of lactones less than 37.4% (area by GPC), the hydroxyalkyl(meth)acrylate composition being represented by formula (1) described below, where R, R1, R2, and R3 are independently a hydrogen or a methyl group, â€œjâ€  is an integer of 2-6, xn pieces of R4 and R5 are independently a hydrogen or an alkyl group having a carbon number of 1-12, â€œnâ€  is an integer greater than or equal to zero, and an average value of â€œnâ€  in the composition is not less than 0.3 to less than 1.0, and (ii) 0.5 parts by weight of a melamine resin (B), wherein the total of (A) and (B) does not exceed 100 parts by weight.
