AQUEOUS ELECTRODEPOSITION COATING, THE PRODUCTION AND USE THEREOF

Document Type and Number:

WIPO Patent Application WO2000034397

Kind Code:

A3

Abstract:

The invention relates to aqueous, anodically electrodepositable coatings which contain A) an aqueous dispersion of anionically modified polyurethane (meth)acrylates (a1) with terminal, ethylenically unsaturated (meth)acrylic double bonds, and reactive diluents (a2) with at least two ethylenically unsaturated (meth)acrylic double bonds, wherein the (meth)acrylate double bonds of the mixture of (a1) and (a2) correspond to a bromine value of 20 to 150 g bromine/100 g solid matter, and B) optionally photoinitiators and/or optionally thermally activatable radical initiators. The terminal ethylenically unsaturated (meth)acrylic double bonds of the polyurethane (meth)acrylate are linked with the anionically modified polyurethane prepolymer via urethane, urea, amide or ester groups. The coating further optionally contains adjuvants and additives, pigments and/or fillers.
