Document Type and Number:
WIPO Patent Application WO/2018/186497
Kind Code:
A1
Abstract:
To provide a hydrophilizing agent which enables the formation of a coating film, said coating film having a high hydrophilicity and excellent water drop removing properties, and a method for forming a hydrophilic coating film. A hydrophilizing agent comprises an aqueous resin dispersion (A) containing an ethylene-vinyl alcohol copolymer (A1) and a carboxylic acid group-containing polymer (A2), which has a structural unit derived from a radical polymerizable carboxylic acid monomer, and crosslinkable fine particles (B), wherein: the ratio by mass [(A1)/(A2)] of the ethylene-vinyl alcohol copolymer (A1) to the carboxylic acid group-containing polymer (A2) is 0.43-2.33; and the ratio by mass [(B)/(A1+A2)] of the crosslinkable fine particles (B) to the sum of the ethylene-vinyl alcohol copolymer (A1) and the carboxylic acid group-containing polymer (A2) is 0.11-1.
