A water-soluble or water-dispersible carbodiimide compound is hydrophilicized by incorporating methyl glycolate or methyl lactate, which serves a moiety similar to the moiety which aqueous urethane resin, aqueous acrylic resin, or the like possesses, into an end of a starting carbodiimide compound. The invention provides a carbodiimide compound and a carbodiimide composition, which, when added as a cross-linking agent to aqueous resin, can enhance water resistance, solvent resistance, and adhesion of the resin, while maintaining the conventionally attained pot life, and an aqueous coating composition containing the carbodiimide compound or composition. |
