Abstract
A method of marking a thermoplastic article can comprise: combining a thermoplastic with a light-marking additive to form a composition, forming the composition into an article having a maximum optical absorption wavelength; and illuminating, at a marking wavelength, at least a portion of the article with a device having a power of less than or equal to about 200 mW, to form a light-mark. The light-mark can have a size, as measured along a major axis, of greater than or equal to about 10 micrometers. The light-mark can also have a mark absorption wavelength that is greater than or equal to about ±100 nm of the maximum optical absorption wavelength, and can have a spectral absorption curve.
