Abstract

The invention relates to the use of a halogen-free multi-layer sheet material comprising (i) a base film of a polymer comprising the reaction product of a precursor mixture comprising at least one hydroxy-functional resin and an aminoplast cross-linking agent; (ii) an adhesive layer; and (iii) optionally, a release liner, as a label or a label stock or in the manufacture of a laser cuttable and/or laser markable article. The invention also relates to the use of a halogen-free film of a polymer comprising the reaction product of a precursor mixture comprising at least one hydroxy-functional resin and an aminoplast cross-linking agent in a laser cuttable and/or laser-markable article.
