SUBSTRATE TREATMENT AGENT AND METAL MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/171194
Kind Code:
A1
Abstract:
Provided is a substrate treatment agent capable of provide a metal material with preferable adhesiveness, acid resistance, and alkali resistance to a laminate film. For the substrate treatment agent, the concentration of a water-soluble metal compound is 500-200,000 mass ppm in terms of metal atoms, a water-soluble or water-dispersible acrylic resin has a number average molecular weight of 70,000-500,000, the solid content has an acid value of 150-740 mgKOH/g and a hydroxyl value of 40-350 mgKOH/g, the water-soluble or water-dispersible acrylic resin has a glass transition temperature in the range of 63-100°C, the concentration of the water-soluble or water-dispersible acrylic resin is 500-200,000 mass ppm in terms of solid content, and the ratio of the concentration of the water-soluble metal compound in terms of metal atoms to the concentration of the water-soluble or water-dispersible acrylic resin is 3/97-91/9. The substrate treatment agent is used in the manufacture of laminated metal materials.
