Abstract
In an embodiment, a method of inscribing a substrate comprises contacting the substrate with a laser beam to generate a mark, wherein the mark results from increasing the reflectivity of the thermoplastic material, wherein the substrate comprises a composition comprising a non-reflective thermoplastic material. In an embodiment, a method for generating a mark on an article comprises bonding a first component to a second component with a laser beam having a wavelength of greater than or equal to 800 nanometers, wherein the first component composition comprises a thermoplastic composition absorbing light having a wavelength of less than or equal to 500 nanometers and wherein the second component comprises a thermoplastic composition absorbing light having a wavelength of greater than or equal to 800 nanometers.
