SUBSTRATE TREATMENT AGENT AND METAL MATERIAL

WIPO Patent Application WO/2022/054667

A1

Provided is a substrate treatment agent that can impart a metal material with favorable adhesion to a laminated film.　This substrate treatment agent contains a water-soluble zirconium compound, a titanium compound and a water-soluble or water-dispersible acrylic resin. The concentration of a water-soluble metal compound is 500-200,000 ppm by mass in terms of metal atoms. The water-soluble or water-dispersible acrylic resin has a molecular weight of 15,000-500,000, a solid content acid value of 150-740 mg KOH/g, and a solid content hydroxyl value of 24-350 mg KOH/g. The concentration of the water-soluble or water-dispersible acrylic resin is 500-200,000 ppm by mass in terms of solid content. The ratio of the concentration of the water-soluble metal compound in terms of metal atoms and the concentration of the water-soluble or water-dispersible acrylic resin is 3/97-91/9. The substrate treatment agent can be used to produce a laminated metal material.
