    Abstract: To provide a process for producing a powder coating material capable of forming a cured film which is excellent in weather resistance and which has few voids (gaps); a coated article having such a cured film; and a method for producing a carboxy group-containing fluororesin less susceptible to gelation. A process for producing a powder coating material containing a powder (X) composed of a composition (a) comprising a fluororesin (A) having carboxy groups, or alkoxysilyl groups and urethane bonds, and a curing agent (D), said process comprising (a) a step of melt-kneading a mixture comprising a hydroxy group-containing fluororesin (B), an acid anhydride (C1) or a compound (C2) having an alkoxysilyl group and an isocyanate group, and the curing agent (D), to obtain a kneaded product composed of the composition (α), and (b) a step of pulverizing the kneaded product to obtain the powder (X).
