aqueous electrophoretic immersion painting, their production and use.

aqueous electrodeposition paint immersion, anodic deposition, containing: (A) an aqueous dispersion containing one or more (meth) acrylates (a1) polyurethane anionically modified with double bonds terminal (meth) acrylic, ethylenically unsaturated, and one or more diluents (a2) reactive with at least two double bonds (meth) acrylic ethylenically unsaturated, corresponding double bonds (meth) acrylic mixture (a1) and (a2) with a bromine index of 20 to 150 g of bromine / 100 g solids, and (B) optionally one or more photoinitiators and / or optionally one or more thermally activatable free-radical initiators, the double bonds terminal (meth) acrylic being bonded, ethylenically unsaturated (meth) acrylate polyurethane through urethane groups, urea, amido or ester prepolymers anionically modified polyurethane and optionally auxiliaries and additives, pigments and / or fillers, containing dispersion A) aqueous 40 to 85% by weight of component a1) and 15 to 60% by weight of component a2), in each case based on the solids content of component A) and the content solid 30 to 70% by weight, and the dispersion a) aqueous being obtainable by preparing the (meth) acrylate a1) polyurethane, by producing a urethane prepolymer with terminal NCO groups, by reacting : i) one or more aliphatic, cycloaliphatic araliphatic and / or aromatic polyisocyanates, ii) one or more polyhydroxyl compounds with an average molecular weight Mn of from 400 to 5000, iii) one or more compounds with one anionic group and two isocyanate functional groups, iv) optionally one or more polyhydroxyl compounds with an average Mn molecular weight of 60 to below 400, and subsequent reaction of the urethane prepolymer thus obtained v) with a oo various compounds containing UNOO various (meth) acrylic ethylenically unsaturated and one or more reactive groups to isocyanate, selected from (meth) acrylates, (meth) aminoalkyl acrylates and / or (methyl) acrylamides, and / or one or more compounds having a group reactive with isocyanate and a group suitable for the introduction of an ester group (meth) acrylic acid and subsequent reaction for the introduction of an ester group (meth) acrylic, vi) and optionally with one or more compounds with one or more reactive groups to isocyanate, which have no double bond (meth) acrylic, after which the reagent is diluted with a2) is carried diluent and the aqueous phase at least partially neutralized.
