ABSTRACT:
A powder coating is provided which does not require a long complicated production process, can be produced easily and with no danger of gelling occurring during production, and which forms a paint film with superior smoothness and with no film defects such as bubbles or pinholes. 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 the curable reactive group of the main constituent resin (A), and an organic solvent (C), is spray dried at a temperature at which the main constituent resin (A) and the curing agent (B) undergo no substantial curing reaction.
