Patent ID: 6914087

Claim:
A method of producing a powder coating, wherein a powder coating raw materials solution comprising as essential constituents a room temperature solid main constituent resin (A) with a curable reactive group, a room temperature solid curing agent (B) which reacts with said curable reactive group of said main constituent resin (A), and an organic solvent (C) incorporating a high boiling point organic solvent (C1) with a boiling point at atmospheric pressure of 150 to 300° C., is spray dried at a temperature at which said main constituent resin (A) and said curing agent (B) undergo no substantial curing reaction, an moreover under conditions where either one of a portion of, and all of, said high boiling point organic solvent (C1) remains, yielding a powder coating in which a percentage content of said high boiling point organic solvent (C1) is from 0.005 to 1% by weight, and wherein the amount of said high boiling point organic solvent (C1) used is from 0.005 to 1 part by weight relative to 100 parts of solid matter in the powder coating raw materials solution.
