Patent ID: 7935746

Claim:
A powder coating suspension prepared by a method comprising (1) emulsifying a liquid component comprising a liquid starting product in an aqueous medium in the presence of an emulsifier whose aqueous solution at the critical micelle concentration (CMC) has a surface tension >30 mN/m to give an aqueous emulsion of liquid particles and (2) cooling the emulsion to solidify said liquid component so that a suspension of dimensionally stable particles is formed; wherein the emulsifier is selected from the group consisting of copolymers prepared by copolymerization in an aqueous medium of a) at least one olefinically unsaturated monomer and b) at least one olefinically unsaturated monomer different than the olefinically unsaturated monomer (a) and of the general formula I R 1 R 2 C═CR 3 R 4 (I) wherein the radicals R 1 , R 2 , R 3 , and R 4 are each independently of one another at least one hydrogen atom, substituted or unsubstituted alkyl, cycloalkyl, alkylcycloalkyl, cycloalkylalkyl, aryl, alkylaryl, cycloalkylaryl, arylalkyl or arylcycloalkyl radicals with the proviso that at least two of the variables R 1 , R 2 , R 3 , and R 4 are substituted or unsubstituted aryl, arylalkyl or arylcycloalkyl radicals.
