PROBLEM TO BE SOLVED: To provide an anion-type electrodeposition paint having an appearance and performance of a coating film suitable for an aluminum material, and particularly excellent in scratch resistance, and a method of electrodeposition coating the same. (A) An α, β-ethylenically unsaturated carboxylic acid monomer, a hydroxyl group-containing α, β-ethylenically unsaturated monomer, and another α, β-ethylenically unsaturated monomer are commonly used. An anion-type electrode comprising: a polymerized vinyl copolymer having an acid value of 10 to 150 and a hydroxyl value of 20 to 200; (B) an amino resin; and (C) hard resin fine particles containing methyl methacrylate or styrene as a main component. Coating paint and its electrodeposition coating method. |
