Abstract
Disclosed is a carboxy group-containing aqueous resin composition containing a carboxy group-containing aqueous resin and a polycarbodiimide compound (X) represented by the following general formula (1): wherein R1 represents a residue obtained by removing a functional group capable of reacting with an isocyanate from a hydrophilic compound having the functional group capable of reacting with an isocyanate; R2 represents a divalent residue obtained by removing isocyanate groups from a diisocyanate compound; R3 represents a divalent residue obtained by removing hydroxy groups from a glycol compound; X represents a group to be formed through a reaction between the hydrophilic compound and the diisocyanate compound; n1 represents a number of 1 to 10; n2 represents a number of 1 to 10; m represents a number of 1 to 5; and plural R1's may be the same or different and plural R2's may be the same or different.
