Abstract
Aqueous primary dispersions and coating materials comprising dispersed and/or emulsified, solid and/or liquid polymer particles and/or dispersed solid core shell particles having a diameter≦500 nm preparable by controlled free-radical microemulsion or miniemulsion polymerization of A) at least one olefinically unsaturated monomer and B) at least one olefinically unsaturated monomer which is different than the olefinically unsaturated monomer (A) and has the general formula I: RRC═CRR(I), in which the radicals R, R, Rand Rindependently of one another are hydrogen atoms or 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, R, Rand Rare substituted or unsubstituted aryl, arylalkyl or arylcycloalkyl radicals, especially substituted or unsubstituted aryl radicals; and in the presence of (C) at least one hydrophobic cross-linking agent for the copolymer resulting from the starting products (A) and (B).
