し、実用的でない。2. Description of the Related Art Hydrophilization of stainless steel has been established as a coating pretreatment technique such as pickling and degreasing. However, although pickling shows good hydrophilicity at the initial stage, even if it is left indoors, it deteriorates rapidly due to aging and returns to the level before pickling. Even in the case of the coating type chromate treatment, it shows good hydrophilicity at the initial stage, but gradually deteriorates with the passage of time and cannot maintain sufficient hydrophilicity. A coating utilizing the photocatalytic effect of titanium oxide exhibits good hydrophilicity under ultraviolet irradiation, but requires an ultraviolet lamp for indoor use and is not practical.

In JP-A-63-171683, water glass and polyacrylamide are applied as a hydrophilizing agent. In JP-A-63-171684, water glass, a mixed copolymer of acrylamide and acrylic acid, is applied as a hydrophilizing agent. In JP-A-8-60031, water-dispersible silica, an aqueous polyurethane resin, and an aqueous blocked urethane prepolymer are applied as hydrophilic treatment agents. But,
These methods have no problem in applications such as plate fins for room air conditioners, but in applications such as washing machine baskets and dishwashers, the problem of corrosion of the base aluminum and generation of white rust cannot be avoided.
