Powder paints containing aluminum and nickel II

In a powder paint which exclusive of catalysts, antistatic agents, plasticizers and flow control agents, the same being known and optional additives to powder paints, consists essentially of aluminum flakes, non-metal pigment and a particulate, organic, film-former, the improvement wherein

• A. said non-metal pigment comprises 0 to about 22 weight percent of said powder paint,
• B. said aluminum flakes comprise about 0.005 to about 25 weight percent of said powder paint and are encapsulated prior to admixture with said particulate, organic, film-former with about 2 to about 200 parts by weight of a continuous coating of a thermoplastic organic, film-former per 100 parts by weight aluminum flakes, said thermoplastic, organic, film-former consisting essentially of thermoplastic, organic film-formers selected from the group consisting of
• 1. polymers of alpha-beta olefinically unsaturated monomers of which about 51 to about 100 weight percent are acrylic monomers aid 0 to about 49 weight percent are monovinyl hydrocarbons,
• 2. polyamides,
• 3. polyesters,
• 4. homopolymers of monovinyl hydrocarbons,
• 5. cellulose acetate, and
• 6. cellulose butyrate,
• C. nickel powder is dispersed in said powder paint, the weight ratio of said nickel powder to the encapsulated aluminum flakes being between about 1:4 and about 5:1, and
• D. said particulate, organic film-former is
• 1. a thermoplastic, particulate, film-former that is a polymer of alpha-beta olefinically unsaturated monomers of which about 51 to about 100 weight percent are acrylic monomers and 0 to about 49 weight percent are monovinyl hydrocarbons, and
• 2. thermosettable, particulate, film-formers consisting essentially of a copolymer having average molecular weight (M.sub.n) in the range of about 1500 to about 15,000 and gloss transition temperature in the range of about 40.degree.C. to about 90.degree.C., bearing functional groups provided by constituent monomers selected from the group consisting of glycidyl esters of a monoethylenically unsaturated carboxylic acid, C.sub.5 - C.sub.7 monohydroxy acrylates, C.sub.5 - C.sub.7 monohydroxy methacrylates and alpha-beta olefinically unsaturated amides and wherein at least above 50 weight percent of the constituent monomers are acrylic monomers and the remainder weight percent, if any, of the constituent monomers consist essentially of C.sub.8 - C.sub.12 monovinyl hydrocarbons, said copolymer being self-crosslinkable or employed in combination with a monomeric or polymeric crosslinking agent that is capable of reacting with said functional groups on said copolymer.
