PROBLEM TO BE SOLVED: To obtain an electrodeposition coating material which exhibits good adhesion to a substrate, is excellent in water resistance, water-repellent and oil-repellent properties, abrasion resistance, and stainproof properties, and has a low coefficient of friction by compounding specified amounts of a (meth)acrylic acid copolymer, a blocked isocyanate, a polysiloxane resin, a fine fluororesin powder, and an organic acid. SOLUTION: This material comprises 72-28 pts.wt. (meth)acrylic acid copolymer, 18-42 pts.wt. blocked isocyanate, 10-30 pts.wt. polysiloxane resin, 10-50 pts.wt. fine fluororesin powder, and an organic acid for neutralizing the foregoing ingredients. The copolymer is formed from 10-80% fluoroalkyl (meth) acrylate of the formula, 5-30% (meth)acrylic acid amino derivative, 5-30% (meth) acrylic acid hydroxy derivative, and 10-30% styrene or (meth)acrylic ester. In the formula, R1 is -H or -CH3; and R2 is -CH2CF3, -CH2(CF2)nCF2H (wherein n is 1 or 3), -CH(CF3)2, or the like.
