ABSTRACT:
The present invention provides a hydrophilic resin composition which is obtained by adding, to a hydrophilic resin selected from a carboxyl group-containing hydrophilic acrylic copolymer resin, a carboxyl group-containing hydrophilic polyester resin and a carboxyl group-containing hydrophilic polyurethane resin, a hydrophilic carbodiimide represented by the following general formula (1): ##STR1## (wherein n is an average polymerization degree and is an integer of 1-30; m is an integer of 4-30; R.sub.1 is a lower alkyl group; and R.sub.2 is a hydrogen atom or a methyl group) and which has an acid value based on the carboxyl group of the hydrophilic resin, of 10-400 mg KOH/g and a molar ratio of the carbodiimide group to the carboxyl group, of 0.2-5.0.
