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: Colorant-containing aqueous polymer dispersions comprise (all amounts by wt. of polymer matrix): (A) (i) a polymer matrix based on an ethylenically-unsaturated monomer (M); and (ii) an organic colorant comprising a dye or pigment, UV-absorber or optical brightener uniformly dispersed in the polymer matrix (0.5-50%); (B) a nonionic surfactant (0.1-20%); and (C) an amphiphilic polymer with 0.5-10 mol./kg anionic-functional groups (1-50%). An Independent claim is also included for preparation of the dispersions by: (i) dissolving the colorant in monomer M, (ii) emulsifying the mixture to give a conventional oil-in-water emulsion, (iii) homogenizing to give a mini-emulsion with monomer droplets of average diameter below 1,000 nm and then (iv) polymerizing the mini-emulsion in presence of a soluble free-radical initiator together with (B) (0.1-20 wt.%) and (C) (1-50 wt.%), each wt. being based on the wt. of M.
