ABSTRACT:
Improved powder coating compositions are disclosed which comprise a particulate mixture of (1) a qualitatively difunctional copolymer of about 5 to about 20 weight percent of a glycidyl ester of a monoethylenically unsaturated acid, about 2 to about 10 weight percent of an alpha-beta olefinically unsaturated amide selected from acrylamide and methacrylamide and about 70 to about 93 weight percent monoethylenically unsaturated monomers consisting essentially of monofunctional monomers selected from the groups consisting of esters of a C.sub.1 - C.sub.8 monohydric alcohol and acrylic acid, esters of a C.sub.1 - C.sub.8 monohydric alcohol and methacrylic acid and C.sub.8 - C.sub.12 monovinyl hydrocarbons, and (2) a carboxy-functional crosslinking agent is a carboxy-terminated compound selected from the group consisting of esters of a diepoxide and a dicarboxylic acid and carboxy-terminated, saturated polyesters.
