Title:

PRE-COATED ALUMINUM MATERIAL

Document Type and Number:

WIPO Patent Application WO/2020/022213

Kind Code:

A1

Abstract:

This pre-coated aluminum material (1) has an aluminum plate (2), a chemical coating (3), and a hydrophilic coating (4) laminated sequentially. The hydrophilic coating (4) contains at least an acrylic resin (A), a polyalkylene ether resin (B), a resin (C), and polyvinyl alcohol (D). The acrylic resin (A) is substantially free from repeating units derived from sulfo group-containing monomers and amide group-containing monomers. The resin (C) has a repeating unit derived from an amide group-containing monomer. The hydrophilic coating (4) has two peaks within the wavenumber range of 1600 to 1800 cm-1 in an infrared absorption spectrum. The absorbance ratio of the peaks satisfies a predetermined relationship.
