Abstract

The present invention relates to a specific radiation-curable coating composition for improving the surface adhesion of plastic parts and its uses as a primer coat, as a base coat or as a clear coat. The composition may be pigmented or unpigmented and may be cured by UV and/or EB. The invention also relates to cured coating resulting from this cure and to the coated plastic substrate with improved surface adhesion.
