Powder coating compositions are disclosed which comprise a blend of coreactable, thermosettable copolymers one of which has at least two different functional groups while the other is qualitatively monofunctional and quantitatively polyfunctional. Ordinarily, the polymer having at least two different functional groups, will be quantitatively polyfunctional and qualitatively difunctional although it may contain more than two different functional groups. In the preferred embodiments, the first or difunctional copolymer of the blend has either (1) epoxy functionality and amide functionality, (2) epoxy functionality and hydroxy functionality, (3) carboxy functionality and amide functionality, or (4) carboxy functionality and hydroxy functionality and is crosslinkable with the second copolymer through at least two different types of functional groups on the first copolymer. The second copolymer has only one type of functionality that is crosslinkable with the functional groups on the first copolymer and may be termed the monofunctional copolymer although it is quantitatively polyfunctional. The second copolymer may have as its functionality (1) anhydride functionality, (2) carboxy functionality or (3) epoxy functionality.

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 difunctional monomers selected from C. sub. 5 -C. sub. 7 hydroxyalkyl acrylates and C. sub. 5 -C. sub. 7 hydroxyalkyl methacrylates, and about 70 to about 93 weight percent monoethylenically unsaturated monomers consisting essentially of monfunctional monomers selected from the group 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) an anhydride crosslinking agent selected from the group consisting of monomeric anhydrides of dicarboxylic acids and homopolymers of monomeric anhydries of dicarboxylic acids, the same being present in an amount such as to provide about 0. 3 to about 1.

Powder coating compositions are disclosed which comprise a blend of coreactable, thermosettable copolymers each of which have at least two different functional groups. Ordinarily, these polymers will be qualitatively difunctional, although they may contain more than two different functional groups, and quantitatively polyfunctional. At least one of the copolymers has epoxy functionality as one of its two or more different functionalities. Thus, in the preferred embodiments, the first copolymer of the blend has epoxy functionality and a second functionality selected from amide functionality, anhydride functionality and hydroxy functionality and is crosslinkable with the second copolymer through at least two different types of functional groups on the first copolymer. The second copolymer also is crosslinkable with the first copolymer though at least two different types of functional groups on the second copolymer and may be (a) anhydride functional and carboxy functional, (b) carboxy functional and amide functional, (c) carboxy functional and hydroxy functional, (d) epoxy functional and amide functional or (e) epoxy functional and anhydride functional. The second copolymer is advantageously employed in an amount such that its functionality of greatest concentration provides about 0.
