PURPOSE:To obtain the titled material capable of forming a coating film which is outstanding in dent resistance improved in gloss and bending processability when coated on a metal base plate, by incroporating a fluorocarbon polymer resin of specified melting point in a thermoplastic aromatic polythersulfone resin. CONSTITUTION:The objective coating material can be obtained by incorporating (A) 100pts. by wt. of a thermoplastic aromatic polyethersulfone resin [e.g., a resin constituted of recurring unit of formula (n is 2-1,000)] with (B) 20-800pts. by wt. of a fluorocarbon, polymer resin with the melting point regulated between 280 and 315 deg.C (pref. a copolymer from tetrafluoroethylene and perfluoroalkyl perfluorovinyl ether). The thickness of the resultant coating film is pref. 10-20mu on a dry basis.
