Abstract

The present invention relates to aqueous polymer-silicon oil hybrid compositions in the form of aqueous dispersions of finely divided polymer-silicon oil hybrid particles which comprise at least one water-insoluble polymer P made of ethylenically unsaturated monomers M, at least one surface-active substance and at least non-polymerizable, non-polar silicon oil. The present invention relates in particular to the use of these compositions as additives in aqueous coating and printing ink compositions.
