Abstract
There is disclosed a method of laser-marking plastic articles without unduly damaging the plastic. The method comprises coating the plastic with a contrasting color layer, and intermediate the color layer and the plastic, a protective layer of a dried coverage of at least 1.5 g/m.sup.2. Optionally, the ablation can be carried out beyond the stripe portion to be marked, to clear away any debris from the white support that otherwise can be left behind by the ablation.
