Disclosed is a method of producing a powdery coating material by using
a curable acrylic resin (A) having a number average molecular weight of from 2,000
to 20,000 and a glass transition temperature of from 30 to 90 C. obtained
by polymerizing a starting monomer containing from 15 to 50 mol % of an unsaturated
compound which contains at least a glycidyl group and/or a methylglycidyl group,
and from 20 to 50 mol % of methyl methacrylate; a curing agent (B) capable of being
reacted with the glycidyl group or the methylglycidyl group constituting the curable
acrylic resin (A); and an alcohol solvent (C) having a boiling point under normal
pressure of from 70 to 120 C.; said method comprising a kneading step of
so kneading the curable acrylic resin (A), the curing agent (B) and the alcohol
solvent (C) that at least the curing agent (B) is dissolved in the alcohol solvent
(C) at a temperature of not higher than 130C., and a vapor-removing step
of continuously vapor-removing the alcohol solvent (C) under a reduced pressure
at a temperature of not higher than 130 C.
