Patent ID: 8476376

Claim:
A powder-lacquer composition, comprising: A) at least one carboxylate-group-containing polymer having an acid number of 5 to 250 mg KOH/g and a glass transition temperature T g higher than 40° C., and B) at least one β-hydroxyalkylamide having two or three or four β-hydroxyalkylamide groups per molecule of formula I wherein R 1 , R 2 : independently of one another denote the same or different radicals, selected from the group consisting of alkyl radicals, cycloalkyl radicals, aryl radicals, aralkyl radicals and alkenyl radicals having 1-24 carbon atoms, wherein the radicals optionally contain a heteroatom and/or a functional group and wherein R 1 may also be hydrogen, and wherein R 2 may also be and A is selected from the group consisting of A 1 and A 3 : wherein R 3 : independently of one another denote the same or different radicals, selected from the group consisting of hydrogen, alkyl radicals, cycloalkyl radicals, aryl radicals, aralkyl radicals and alkenyl radicals having 1-24 carbon atoms, wherein the radicals optionally contain a heteroatom and/or a functional group and wherein two or more R 3 substituents optionally are linked to one another to form a ring; wherein the β-hydroxyalkylamide exists in solid form below 150° C.; C) optionally, a processing aid and/or an additive; wherein the ratio of β-hydroxyalkylamide groups to the carboxylate groups ranges between 0.5:1 and 1.5:1.
