Abstract
This invention relates to a process for hydrophilic treatment of an aluminum material comprising a step for priming in which a primer containing the nitrate or related compound of a metal selected from aluminum, zirconium, cerium, chromium, and iron is applied to the surface of an aluminum material so that the amount of adhering metal becomes 1.0 mM/m or more and then the primer is baked at the specified temperature and a step for coating in which a hydrophilic coating is applied to the primer film formed in said step for priming and then baked at the specified temperature. This invention also relates to primers and hydrophilic coatings useful for the aforementioned treatments. It is possible to form a hydrophilic film, with pronounced hyrdophilicity particularly after press forming, on the surface of an aluminum material.
