HYDROPHILIZATION TREATMENT AGENT AND METHOD FOR FORMING HYDROPHILIC COATING FILM

Provided are: a hydrophilization treatment agent; and a method for forming a hydrophilic coating film, which are capable of forming a coating film which has excellent hydrophilicity and water droplet removal properties and can maintain the excellent water drop removal properties.A polyetheramine is added to a specific aqueous resin dispersion and crosslinkable fine particles in a specific composition. Specifically, this hydrophilization treatment agent contains an aqueous resin dispersion (A), crosslinkable fine particles (B), and a polyetheramine (C), wherein: the aqueous resin dispersion (A) contains an ethylene-vinyl alcohol copolymer (A1) as a resin solid content and a radical polymer (A2) having a structural unit derived from a radically polymerizable carboxylic acid monomer (A2-1); ((A1)/(A2)) is 0.43-2.33; ((B)/(resin solid content of (A)) is 0.11-1.43; and ((C)/((resin solid content of (A))+(B))) is 0.1-0.38. 本发明提供能够形成在亲水性和水滴去除性优异的同时可以维持优异的水滴去除性的皮膜的亲水化处理剂和亲水皮膜的形成方法。在特定的水性树脂分散体和交联性微粒中进一步以特定组成配合聚醚胺。具体而言
