AQUEOUS ELECTRODEPOSITION PAINTS AND THE PRODUCTION AND USE THEREOF

摘要

The invention relates to an aqueous, cathodically separable electrodeposition paint comprising A) an aqueous dispersion made of cationically modified polyurethane(meth)acrylates (a1) having terminal, ethylenically unsaturated (meth)acrylic double bonds and a reactive diluent (a2) having at least two ethylenically unsaturated (meth)acrylic double bonds, whereby the (meth)acrylatic double bonds of the mixture consisting of (a1) and (a2) correspond to a bromine number of 20 to 150g bromine/100g solid body and B) photo initiators and optionally thermally activable radical initiators, whereby the terminal ethylenically unsaturated (meth)acrylic double bonds of the polyurethane(meth)acrylates are connected to the anionically modified polyurethane prepolymer by means of urethane-, urea-, amide- or ester groups, and optionally conventional auxiliary and additional means, pigments and/or fillers.
