摘要： An optical recording material possesses a light-absorbing layer on a base, the said layer containing one or more colorants of the formula (I) ##STR1## where M is two hydrogen atoms or Fe, Cu, Co, Ni, Pb, Cr, Mn, VO, TiO, ZrO, Nb, Ta, Pd, SiCl.sub.2, Sn or SnX.sub.2, X is Cl, Br or I, and A is a divalent radical of an unsaturated, unsubstituted or substituted carbocyclic ring system.The colorants (I) present on the novel recording materials have a high absorption in the range from 650 to 850 nm and accordingly can be written on and read by means of a laser. The colorants can be applied as 20-1000 nm layers on a suitable base by vapor deposition or as a solution or dispersion, with or without the addition of a polymeric binder, by a conventional method.The layers are very stable to atmospheric influences and daylight.
