ABSTRACT:
The present invention relates to a coating composition which is suitable for coating plastics and contains a one- or two-component binder and, as an adhesion promoter, a chemically modified crystalline, chlorine-free polyolefin, which has an average molecular weight of 1,000 to 8,000, a non-uniformity of 1.0 to 6.5 and a content of nitrogen, oxygen, sulphur and/or silicon in the form of chemically incorporated functional groups of 1.5 to 17.5 wt % in total. The present invention also relates to a process for coating plastics using this coating composition and to the resulting coated plastics.
