Document Type and Number:
WIPO Patent Application WO/2020/179835
Kind Code:
A1
Abstract:
Provided are: a carbodiimide-based aqueous resin crosslinking agent which, when a crosslinking agent and an aqueous resin are used in combination, has excellent storage stability and can also make a cured product of the aqueous resin have various improved physical properties such as solvent resistance or water resistance; an aqueous resin crosslinking agent-containing liquid containing the same; and an aqueous resin composition. This aqueous resin crosslinking agent contains a predetermined polycarbodiimide compound (A) having an oxyalkylene group, a predetermined polycarbodiimide compound (B), and a surfactant (C), wherein: each polycarbodiimide compound has, at both ends thereof, a structure in which an isocyanate group is blocked with a predetermined end-sealing compound; the total content of the oxyalkylene group in (A) is 15 mass% or more; the total content of the oxyalkylene group in (A) and (B) with respect to the total amount of (A) and (B) is 10 mass% or less; and the content of (C) is 0.1-20 parts by mass with respect to 100 parts by mass of the total content of (A) and (B).
