Title:
AQUEOUS RESIN CROSSLINKING AGENT, AQUEOUS RESIN CROSSLINKING AGENT-CONTAINING LIQUID, AND AQUEOUS RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2022/045023
Kind Code:
A1
Abstract:
Provided are: a carbodiimide-based aqueous resin crosslinking agent which exhibits excellent storage stability in an aqueous medium, exhibits excellent storage stability when an aqueous resin is also present, and can improve the flexibility and solvent resistance of a cured product of an aqueous resin; and an aqueous resin crosslinking agent-containing liquid and an aqueous resin composition containing same. This aqueous resin crosslinking agent contains polycarbodiimide compounds (A) and (B). The polycarbodiimide compound (A) is a structure in which isocyanate groups at both terminals are capped with a prescribed hydrophilic organic compound. The polycarbodiimide compound (B) contains a linear diisocyanate compound as a structural unit and is a structure in which isocyanate groups at both terminals are capped with a prescribed organic compound. The amount of the polycarbodiimide compound (A) is 5-90 parts by mass relative to a total of 100 parts by mass of the polycarbodiimide compounds (A) and (B).
