Abstract: The invention relates to a process and the product obtainable by the process for the preparation of an aqueous anionically stabilized polymer dispersion comprising a first emulsion polymerization of a first monomer mixture comprising acid functional monomers and substantially no amine functional monomers to form a the first phase oligomer, neutralising and a second emulsion polymerisation in the presence of the emulsion of the first phase of a second monomer mixture comprising amine functional monomers having sterically hindered secondary amine or tertiary amine groups and substantially no acid functional monomers to form a second phase of an amine functional polymer wherein the two phases are unmixed and separate. The invention further relates to the dispersions further comprising reactive and/or non-reactive co-binder, in particular polyepoxide co-binder and also relates to the use of the dispersions for preparation of coating compositions and coatings with anti-bleeding properties.

Abstract: The present invention relates to a crosslinkable composition crosslinkable by Real Michael Addition (RMA) reaction comprising a component with at least 2 activated unsaturated groups (hereafter referred to as the RMA acceptor groups) and a component with at least 2 acidic protons C—H in activated methylene or methine groups (hereafter referred to as the RMA donor groups) which components can react to form a crosslinked network. The composition comprises f. Component(s) A having at least 2 acidic C—H donor groups in activated methylene or methine and having a pKa(A) between 10.5 and 14, g. Component(s) B having at least 2 activated unsaturated acceptor groups, wherein a molar ratio R of acceptor groups to donor groups is between 3:1 to 1:6 and which component(s) B react with component(s) A by Real Michael Addition (RMA) to form a crosslinked network, h. basic component(s) C being a salt of a basic anion X— from an acidic X—H group containing compound wherein X is N, P, O, S or C, iv. in an amount xc between 0.001 and 1 meq/(gr of components A, B, C, D), v. anion X— being a Michael Addition donor reactable with component B and vi. anion X— is characterized by a pKa(C) of the corresponding acid X—H of more than two units lower than the pKa(A) of the majority component A and being lower than 10.5, i. optional component(s) D comprising one or more acidic X′—H groups wherein X′ is N, P, O, S or C, v. X′ being a same or different group as group X in component C, vi. the X′— anion being a Michael Addition donor reactable with component B, vii. the pKa(D) of the X′—H group in component D being more than two units lower than pKa(A) of the majority component A and being lower than 10.5, viii. the equivalent ratio Rd/c of acidic X′—H groups in component D over basic anion X— in component C is between 1% and 5000%,
