Abstract
A ultraviolet-curable coating agent contains: a hydrophilic polymer having the specific structure represented by the following general formula (1); a polymerization-reactive urethane oligomer; a water-soluble monomer; a photo polymerization initiator; and a water-absorptive filler. The polymerization-reactive urethane oligomer is preferably formed of a carboxyl-group-containing dihydroxyl compound, polymer polyol, organic diisocyanate compound and hydroxyl-group-containing acrylic ester, and a number average molecular weight of the polymerization-reactive urethane oligomer is preferably 1000 to 10000. By applying the ultraviolet-curable coating agent onto a front face of a substrate, an ink-receiving layer having excellent ink absorptivity, drying characteristics of printed images, bleeding resistance, anti-tacking and water resistance can be formed.where: P represents an integer of 2 or more;;+1 (in which m is an integer of 1 to 8);— (in which n is an integer of 1 to 8); and+1 (in which o is an integer of 1 to 8).body.
