摘要： Thermoset paint compositions with which paint films can be formed which have excellent acid resistance, abrasion resistance and adhesion, and with which the water repelling properties and staining resistance can be retained for a longer period of time than with the conventional fluorine resin based paint films, are obtained. Constitution: Thermoset paint film compositions which contain (a) from 20 to 80% by weight of fluorine containing copolymer, comprising fluoro-olefin and vinyl based monomer, of which the solubility parameter value is from 9.0 to 10.5 and the hydroxy group value is within the range from 60 to 150 mgKOH/g; (b) from 20-80% by weight of vinyl based (co)polymer, comprising vinyl based monomer which contains at least 10% by weight of monomer which can be repesented by formula (1), of which the solubility parameter is from 9.0 to 10.5 and the hydroxy group value is within the range from 60 to 150 mgKOH/g; (c) from 5 to 40% by weight of alkyl etherified melanine resin; and (d) from 2 to 40% by weight of blocked polyisocyanate compound, and with which the glass transition temperature of the paint film after hardening is at least 50° C. In formula (1), R1 to R5 each independantly represent H or methyl group, i is 0-2, j is 0 or 1, k is 0-3, m is 0-3 and n is 0-10.
