    摘要: The invention relates to aqueous pigment dispersions comprising at least one dispersed pigment, an aqueous carrier and a copolymer prepared by polymerization of at least one macromonomer (1 ) having a terminal olefinic unsaturation with a mixture of olefinically unsaturated monomers (2), wherein the macromonomer (1 ) comprises 1 a) 5 - 100 % by weight of at least one polymerized acid functional unsaturated monomer, 1 b) optionally at least one polymerized hydroxy functional unsaturated monomer, and optionally 1 c) at least one further polymerized olefinically unsaturated monomer, and wherein the mixture of olefinically unsaturated monomers (2) comprises 2a) 5 - 80 % by weight of at least one unsaturated vinyl aromatic monomer, 2b) 5 - 50 % by weight of at least one vinyl monomer with at least one polar heterocyclic group with a 5 or 6 membered ring containing at least one ring nitrogen atom which is not connected to a hydrogen atom, and optionally 2c) other olefinically unsaturated monomers.

    摘要: A process for the production of multi-layer coatings in A' color shades, comprising the successive steps: 1 ) applying a base coat layer in a total process film thickness in the range from 10 to 35 μm to a substrate provided with an EDC primer, 2) applying a clear coat layer onto the base coat layer, 3) jointly curing the base coat and clear coat layers, wherein the base coat layer is applied in a first layer of a modified water-borne base coat modAB prepared by mixing an unmodified water- borne base coat A with an unmodified water-borne base coat B and with a pigment-free admixture component and in a second layer of the unmodified water-borne base coat A.

    摘要: A process for multilayer repair coating, comprising the following steps: applying a first base coat layer of a conventional, water-borne base coat I containing at least one special effect pigment, applying a second base coat layer of a water-borne base coat II onto the resultant coating, wherein the water-borne base coat II for producing the second base coat layer is feathered out into the zones bordering the repair coating, and wherein this water-borne base coat II comprises A) at least one water-dilutable binder, B) at least one special effect pigment, C) at least one matting agent, D) water and E) optionally, conventional coating additives and/or organic solvents, with the proviso that the water-borne base coat II contains the at least one special effect pigment in a quantity of 25 75 wt.%, relative to the quantity of the at least one special effect pigment contained in water-borne base coat I, applying a clear coat layer of a transparent clear coat onto the resultant coating and curing the coating applied.
