Abstract: The invention relates to a method for producing aqueous polymer dispersions containing colorants by radical aqueous emulsion polymerisation of ethylenically unsaturated monomers in the presence of radical-forming initiators. At least a proportion of the monomers is used in the form of an oil-in-water emulsion E1 whose disperse phase contains at least one oilsoluble colorant. The inventive method is characterised in that the disperse phase of E1 is essentially made up of colorant-containing monomer droplets with a diameter

Abstract: In the production of aqueous polymer dispersions by free radical emulsion polymerisation of monomers, a mini-emulsion (I) is added before or during polymerisation. (I) is an aqueous emulsion, stabilised with a surfactant, which contains emulsified monomer droplets with a particle size of 10-500 nm and a co-stabiliser, dissolved in the monomer, which is at least twice as soluble in the monomer as it is in water. Also claimed are polymer dispersions obtained in this way.

Abstract: The production of polymers comprises the emulsion polymerisation of hydrophobic monomers (a) and optionally water-soluble monomers in the presence of at least one compound (b) which is capable of forming a super-molecular structure. Also claimed are aqueous polymer dispersions obtained by the above process.
