Abstract
An active-energy-ray curable coating composition comprising 99 to 50 parts by weight of an acrylic copolymer (A) having (meth)acryloyloxy groups linked to functional groups of side chains and 1 to 50 parts by weight of an unsaturated compound (B) having two or more crosslinkable bonds.

An active-energy-ray curable coating composition comprising
- (i) 99 to 50 parts by weight of an acrylic copolymer (A) having pendant (meth)acryloyloxy groups introduced by the utilization of functional groups of side chains of the acrylic copolymer wherein the functional groups are selected from the group consisting of a glycidyl group, an isocyanate group, a carboxyl group, a hydroxyl group, an acid amide group and an amino group and wherein the acrylic copolymer is obtained by using as a comonomer at least one member selected from the group consisting of ##STR4## wherein each of R.sub.1 and R.sub.2 is a hydrogen atom or a methyl group, and m is zero or an integer of 1 to 4, ##STR5## wherein each of R.sub.3 and R.sub.4 is a hydrogen atom or a methyl group, and n is zero or an integer of 1 to 4;
- and
- (ii) an unsaturated compound (B) having two or more crossinkable double bonds.
