ABSTRACT:
A laser markable sheet having a thermally sensitive base sheet overlaid by a transparent cover sheet. The cover sheet is adhered to the base sheet by a transparent adhesive. Markings may be produced on the base sheet by directing a laser beam through the cover sheet and the transparent adhesive so that the beam impinges on the front surface of the cover sheet. The rear surface of the cover sheet may be coated with a pressure sensitive adhesive, and the pressure sensitive adhesive may be temporarily covered by a release liner.
