Process for coating an electrically conductive substrate and an aqueous coating composition based on a cationic binder.

摘要

A process is provided for coating an electrically conductive sub­strate with an aqueous coating composition containing a cationic binder wherein the binder is obtained by polymerization of 100 parts by weight of a specified monomer mixture in the presence of 0,5 to 25 parts by weight of a polyurethane having 2-5 acryloyl groups or methacryloyl groups, a molecular weight of 400-7000 and a molecular weight per (meth)acryloyl group of at least 200. The invention also pertains to the aqueous composition as such.
