To provide an anionic electrodeposition coating giving both coating film appearance and coating film performance suitable to aluminum materials, and being excellent in scratch resistance in particular.

The anionic electrodeposition coating comprises (A) a vinyl copolymer being prepared by the copolymerization of an ,-ethylenically unsaturated carboxylic acid monomer, a hydroxyl-containing ,-ethylenically unsaturated monomer and another ,-ethylenically unsaturated monomer, and having an acid value of 10-150 KOHmg/g-resin solid content and a hydroxyl value of 20-200 KOHmg/g-resin solid content, (B) an amino resin and (C) dimethylpolysiloxane-based silicone resin particles.
