摘要: The invention relates to aqueous dispersions of cross-linked polymer microparticles, prepared in an medium from a polymer, optionally dissolved organic solvent, said bearing at least two hydroxyl groups and comprising number ionic sufficient for the formation stable dispersion, as component (A) one further (B) elevated temperature, characterized that is polyesterpolyol, polyurethane or polyacrylate having acid value 5 168, aminoplast resin consisting molecules containing reactive and/or amino ether groups, ratio by weight between 30:70 95:5, dispersion usable water solvent mixtures thereof. process producing these dispersions, use thereof coating compositions dispersions.
