The invention relates to aqueous primary dispersions and coating matters containing dispersed and/or emulsified, solid and/or liquid polymer particle s and/or dispersed solid core-shell particles having a particle diameter <= 500 nm. The inventive dispersions and coating matters can be produced by means o f controlled radical micro or miniemulsion polymerisation of (A) at least one olefinically unsaturated monomer and (B) at least one olefinically unsaturat ed monomer of the general formula (I): R1R2C=CR3R4, wherein the radicals R1, R2 , R3 and R4, independently from each other, stand for hydrogen atoms or substituted or unsubstituted alkyl-, cycloalkyl-, alkylcycloalkyl-, cycloalkylalkyl-, aryl, alkylaryl-, cycloalkylaryl-arylalkyl- or arylcycloalkyl radicals, whereby said last monomer is different from the monomer (A), with the proviso that at least two of the variables R1, R2, R3 and R4 stand for substituted or unsubstituted aryl-, arylalkyl- or arylcycloalkyl radicals, especially substituted or unsubstituted aryl radicals, and in the presence of (C) at least one hydrophobe cross-linking agent for the copolymer resulting from the starting products (A) and (B). Th e invention also relates to the use thereof.
