PURPOSE: To obtain the title composition which gives a film excellent in weatherability and corrosion resistance and is useful for cationic electrodeposition coating by using a specified fluoro-copolymer, a specified fluorine-free resin, and a curing agent as the essential constituents.
CONSTITUTION: The composition contains as the essential constituents a hydroxylated fluoro-copolymer (e.g. a copolymer obtained by reacting chlorotrifluoroethylene, cyclohexyl vinyl ether, ethyl vinyl ether and ω- hydroxybutyl vinyl ether) preferably having a hydroxyl value of 10-230mgKOH/g polymer, a fluorine-free resin containing cationic groups, preferably comprising an amine-modified epoxy, acrylic or polybutadiene resin, and a curing agent (e.g. blocked isocyanate).
