Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an aluminum coating material for a can top having excellent corrosion resistance by combining a titanium-based chemical treatment film having a specific property with a water-based coating material. SOLUTION: In the coating material for aluminum to be used as the can top material by providing a chemical treatment film on the surface of an aluminum or aluminum alloy plate and forming a coated film on this chemical treatment film, the chemical treatment film is composed of a titanium-based chemical treatment film with an amount of the titanium adhered of 3-60 mg/m2, and the coated film contains from 0.1 to less than 1.0 wt.% phenol-formaldehyde resin in terms of the solids content of the coated film. This coating material enables coating by a chromium-free chemical treatment and an organic solvent- free water-based coating material and can contribute to the prevention of environmental pollution.
