Abstract (en)

[origin: DE19726136A1] The invention relates to plastics which can be marked by laser, characterised in that an absorber material in the form of a plastic which is not receptive to laser treatment contains a polymer whose intrinsic properties are such that it can be marked by laser. Said polymer is present in the form of micro-ground particles with a particle size of between 0.1 and 100 mu m.
