In the presence of the emulsifier (A), (1) one liquid component (B) containing at least one liquid or liquefied component of the powder slurry or powder coating is emulsified in the aqueous medium (C), This produces an aqueous emulsion of liquid particles (D), (2) the emulsion is cooled to form a suspension of dimensionally stable particles (D), ie a powder slurry, and (3 ) Dimensionally stable particles (D), i.e. powder slurries and powder paints which can be produced by isolating the powder paint, wherein the emulsifier (A) is 50-250 mg (KOH) (A1) hydroxy group-containing olefinically unsaturated monomer and group (a2): (a21) general formula (I) R 1 R 2 C = CR 3 R 4 (I) (wherein at least two of the substituents Selected from the group consisting of (a22) an olefinically unsaturated terpene hydrocarbon and (a23) a dimeric α-alkylvinylaromatic compound, which represents a substituted or unsubstituted aryl, arylalkyl or arylcycloalkyl group); Powder slurries and powder coatings, which can be produced by radical copolymerization of olefinically unsaturated monomers to be produced; their production process and their use. |
