Abstract: A process for reducing the amount of residual monomer in aqueous polymer dispersions operates by aftertreatment with an initiator system essentially comprisinga) from 0.001 to 5% by weight, based on the total monomer amount used to prepare the polymer dispersion,a1) of an oxidizing agent where R1 is hydrogen or a C1-C8-alkyl or a C6-C12-aryl group, and/ora2) of a compound which in aqueous medium releases hydrogen peroxide, andb) from 0.005 to 5% by weight, based on the total monomer amount used to prepare the polymer dispersion,b1) of an alpha-hydroxycarbonyl compound where R2 and R3 independently of one another are hydrogen and/or a C1-C12-alkyl group which may contain functional groups and/or may be olefinically unsaturated, or R2 and R3 optionally, by way of methylene groups, form a ring structure which may contain functional groups and/or may be olefinically unsaturated, and/orb2) of a compound which in aqueous medium releases such alpha-hydroxycarbonyl compounds, andc) advantageously, catalytic amounts of a polyvalent metal ion which is able to exist in a plurality of valence states.

Abstract: An aqueous, pigment containing composition (I) comprises (A) a copolymer (P) of ethylenically unsaturated monomers (M) in the form of an aqueous polymer dispersion containing 0.1-1.5 wt.% (w.r.t (P)) of itaconic acid as an acidic monomer (M1), its salts and/or anhydride whereby upto 50 wt.% of the itaconic acid maybe replaced by another monomer having at least an acid group or neutralized acid group, and having a glass transition temperature, Tg of ?-10-50 deg C. (B) an organic pigment (C) optionally inorganic filler and (D) conventional processing aids.

Abstract: The invention relates to aqueous pigment preparations containing i) at least one copolymer P of ethylenically unsaturated monomers M in the form of an aqueous polymer dispersion which contains between 0.1 and 1.5 weight %, in relation to the total weight of the copolymer P, of polymerised itaconic acid as acid monomer M1, its salts and/or anhydride, where up to 50 weight % of the itaconic acid can be substituted by another monomer having at least one acid group or a neutralised acid group, and whose glass transition temperature TG lies between -10 and +50 ~C; ii) at least one inorganic pigment; iii) possibly inorganic fillers; and iv) standard additives. The invention also relates to the use of the copolymers P containing itaconic acid for improving the wetabrasion resistance of polymer-bound coatings containing pigments.
