Abstract
An active energy ray-curable resin composition comprises (A) a graft copolymerized polymer comprising graft chains composed mainly of structural units derived from at least one monomer selected from the group consisting of (a) hydroxyl containing (meth)acrylic monomers, (b) amino or alkylamino containing (meth)acrylic monomers, (c) carboxyl containing (meth)acrylic or vinyl monomers, (d) N-vinylpyrrolidone, (e) vinylpyridine or its derivatives and (f) (meth)acrylic amide derivatives represented by the general formula (II) shown below: ##STR1## (wherein R.sub.1 is hydrogen or methyl group and R.sub.2 is hydrogen or an alkyl or acyl group having 1 to 4 carbon atoms which may have hydroxyl group added to trunk chains composed mainly of structural units compsiting at least one monomer selected from the group consisting of the monomer represented by the general formula (I) shown below: ##STR2## (wherein R.sub.1 to R.sub.8 each represent hydrogen or methyl group), alkyl (meth)acrylates, acrylonitrile and styrene, and (B) a monomer having an ethylenically unsaturated bond.
