Abstract: The invention relates to a polymer composition (P), comprising at least one acrylonitrile-butadiene-styrene copolymer (A) (ABS copolymer (A)), characterized in that the polymer composition (P) has a surface energy of >38 dyne/cm. The invention further relates to a process for painting a surface of a polymer moulded article comprising the polymer composition (P), wherein no pre-treatment of the surface of the polymer moulded article, such as primer coating, is required prior to the application of the paint.
