ABSTRACT:
The invention provides a composition and method for obtaining both light and dark laser marks of varying shades and intensities on a single plastic article by selectively controlling laser parameters. The invention further provides compositions and methods for obtaining pre-selected one-color and multi-colored designs on plastic articles, by selectively controlling material formulations and laser parameter settings.
