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 oil-soluble 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 a process for preparing a final aqueous polymer dispersion having a solids volume concentration of 50% by volume or more, free-radically polymerizable monomers other than vinyl or vinylidene halides are subjected to a free radical aqueous emulsion polymerization by the feed stream addition process in the presence of an aqueous starting polymer dispersion whose dispersed starting polymer particles have a certain minimum diameter.
