The present invention generally relates to a method of laser-marking. The method can include exposing a precursor to a laser creating a mark. The precursor can include a polymer or plastic loaded with a laser-marking additive in an amount of or greater than about 1 wt. %. The additive can include: at least one compound of the formula: MOCl where M is, independently, As, Sb, or Bi; or a compound of the formula BiONO3, Bi2O2CO3, BiOOH, BiOF, BiOBr, Bi2O3, BiOC3H5O7, Bi(C7H5O2)3, BiPO4, Bi2(SO4)3, Pb(OH)2.2PbCO3, or Pb(OH)2.PbCO3.
