Abstract: Dark-colored thermoplastic molding compositions are disclosed. The compositions are suitable for making molded parts which in the wavelength region from 700 to 1200 nm are laser-transmitting, at least in spectral partial regions, and may be welded to laser-absorbing molded parts by means of laser transmissions welding.
