Metallic material with organic composite coating excellent in corrosion resistance and coatability and reduced in finger mark adhesion and process for producingthe same

摘要

A metallic material having a surface excellent in corrosion resistance and coatability and reduced in finger mark adhesion. The coated metallic material comprises a metallic material having on a surface thereof: a first coating layer obtained from (A) a silane coupling agent ingredient having a reactive functional group such as an amino group having active hydrogen or an epoxy group and (B) a polymer ingredient comprising a water-soluble polymer represented by formula (I) having an average degree of polymerization of 2 to 50; and formed on the first layer, a second coating layer made of a resin composition comprising 100 parts by weight of a resin and 5 to 70 parts by weight of silica.
