Zusammenfassung:	2.1. The priming of plastic substrates without any adverse affect on the mechanical stability is described. 2.2. A coating composition comprising from 10 to 35 % by weight of binder having an OH number of from 40 to 150, prepared from (meth)acrylamides, hydroxyalkyl (meth)acrylates and copolymerisable, olefinically unsaturated compounds with subsequent modification by polyisocyanates, up to 20 % by weight of further binders, from 30 to 70 % by weight of organic solvents, from 15 to 45 % by weight of pigments and/or fillers, from 0 to 15 % by weight of additives and from 1 to 30 % by weight of epoxide- or polyisocyanate-based crosslinking agents, is used. 2.3. Painting of plastic parts for motor vehicles.
