Document Type and Number:
WIPO Patent Application WO/2021/205834
Kind Code:
A1
Abstract:
Provided is an aqueous resin composition comprising an acrylic polymer (A), a urethane resin (B), and an aqueous medium (C), in which the acrylic polymer (A) is formed from 2-hydroxyethylacrylamide, an unsaturated carboxylic acid or an anhydride thereof, and a monomer component comprising at least a polyoxyalkylene unit and a monomer having a polymerizable unsaturated group and has a weight average molecular weight of 100,000 or higher. A coating film obtained from the aqueous resin composition can be used suitably in various coating agents because it can exhibit persistent hydrophilicity even under conditions that impose a harsh thermal history and conditions of use after application of a processing oil and washing.
