Abstract: Copolymers of (meth)acrylates and Alpha , Beta monoolefinically unsaturated carboxylic acid having three to five carbon atoms are used as additives for improving levelling, glass and reactivity in powder lacquers. Said powder lacquers contain polymerized units of at least 35% by weight of styrene and (meth)acrylate and 5 to 30% by weight of at least one monomer containing a hydroxyl, carboxyl, glycidyl, N-methylol or Nmethylol ether group. The powder lacquer mixture contains 0.1 to 5% by weight of the additive.
