Abstract

A sheet of material that is marked with a pulsed laser, the sheet of material having an outer edge and an inner edge separated by a core. The distance from the outer edge to the inner edge is the sheet thickness. The sheet of material has a total concentration of TiO2 of less than about 1.00%. There is an exterior layer beginning at the outer edge and extending into the core, the thickness of the exterior layer is from about 10.00% to about 40.00% of the sheet thickness, and the exterior layer has an average concentration of from about 2.50% to about 10.00% TiO2.
