Abstract
A crosslinking agent composition for water-compatible resins which comprises a hydrophobic crosslinking agent, a water-soluble organic compound, one or more oily media selected from among hydrocarbon-based solvents and ketone-based solvents having a solubility parameter of 9.0 (cal/cm−3)1/2 or less, and an aqueous medium. The crosslinking agent composition can improve the storage stability of a water-compatible resin composition. The water-compatible resin composition which contains this crosslinking agent composition can give cured objects satisfactory in terms of water resistance and solvent resistance and is suitable also for use in wet-on-wet coating.

A crosslinking agent composition for water-compatible resins, comprising a hydrophobic crosslinking agent, a water-soluble organic compound, one or more oily medium selected from the group consisting of ketone solvents having a solubility parameter of 9.0 (cal/cm3)1/2 or less and hydrocarbon solvents, and an aqueous medium,
- wherein the oily medium is included in an amount of from 15 to 200 parts by weight per 100 parts by weight of the hydrophobic crosslinking agent,
- wherein the water-soluble organic compound is one or more water-soluble polymer selected from the group consisting of polyvinylpyrrolidone, polyvinyl alcohol, polyethyleneimine, polyacrylic acid, polyacrylamide, carboxymethyl cellulose, starch and gelatin, and
- wherein an amount of the water-soluble organic compound is 0.03 to 50 parts by weight per 100 parts by weight of the hydrophobic crosslinking agent.
