| abstract |
The invention discloses a carboxyl group-containing water-based resin composition, which comprises a carboxyl group-containing water-based resin and a polycarbodiimide compound (X) represented by the following general formula (1). (wherein, R 1 represents a residue from a hydrophilic compound having a functional group reactive with isocyanate from which a functional group reactive with isocyanate is removed, and R 2 represents a divalent residue from a diisocyanate compound from which an isocyanate group is removed group, R 3 represents a divalent residue from which a hydroxyl group is removed from the diol compound. X represents a group formed by the reaction of the hydrophilic compound and the diisocyanate compound. n1 represents a number from 1 to 10, n2 Represents a number from 1 to 10, and m represents a number from 1 to 5. A plurality of R 1 and R 2 are the same or different from each other.) |
