ABSTRACT:
The present invention relates to natural-colored and pigmented thermoplastic molding compositions and molded parts fabricated therefrom that are laser-absorbing at least in partial spectral regions of the wavelength range from 700 to 1200 nm and that can be welded by laser beam welding and to molded parts that are transparent or translucent to laser light.
