Of organic solvents are substantially or completely free, pseudoplastic, curable, aqueous powder dispersions, process for their preparation and their use

Of organic solvents are substantially or completely free, pseudoplastic, curable, aqueous powder dispersions containing dimensionally stable particles (A) with a measured by the laser diffraction method, average particle size of D (v, 0.5) = 1 to 10 microns, wherein the dimensionally stable particles ( a) (as a binder 10 to 100 wt .-% of at least one (meth) acrylate copolymer A1) include having an OH number of 40 to 250 mg KOH / g and an acid number of 5 to 100 mg KOH / g, prepared by multistage copolymerization (A11) hydroxyl group-containing acrylate and / or methacrylate and (A12) acid group-containing, unsaturated monomers olefinically has been prepared in organic solution, where (1) in a stage the total amount or the predominant part of the monomers (a11) optionally with a small proportion of the monomers (a12) (co) has been polymerized, before (2) has been polymerized in a further stage the total amount or the predominant part of the monomers (a12) where appropriate, with the remainder of the monomers (a11) (CO); Processes for their preparation and their use.
