Plastics moulded parts, suitable for the motor vehicle sector, consisting of a transparent plastics material the rear face of which is provided with a colour- and/or effect-producing lacquer.

Decoratively enameled plastic molded parts for motor vehicles

Aqueous coating composition based on polyols with ammonium groups and polyisocyanates, which coating composition may contain pigments and/or extenders, customary lacquer additives and one or more organic solvents, and contains

Processes for coating molded plastic substrates with aqueous coating

A process for priming of plastic substrates without adverse effects on the mechanical stability by applying to a plastic substrate, particularly a polyolefin substrate, a coating composition which comprises from 10 to 35% by weight of binders 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 means of 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.
