ABSTRACT:
Substrates suitable for being marked by light energy from a laser are disclosed. Such substrates include a base substrate component and a filler pigment component coupled to the base substrate component and including a combined metal component and a glass forming component other than the combined metal component. The filler pigment component is present in an amount effective to, as a result of exposing the substrate to light energy from a laser, produce a colored glass-like pigment component coupled to the base substrate component having a contrasting color relative to the filler pigment component. Markings, for example, on electrical wire insulation, having higher contrast and greater durability are advantageously provided.
