Abstract

Optical data carrier comprising a preferably transparent substrate which may, if desired, have previously been coated with one or more reflection layers and/or protective layers and to whose surface a light-writable information layer, if desire one or more reflection layers and if desired a protective layer or a further substrate or a covering layer have been applied, which can be written on and read by means of blue light, preferably light having a wavelength in the range 360-460 nm, in particular from 390 to 420 nm, very particularly preferably from 400 to 410 nm, preferably laser light, where the information layer comprises a light-absorbent compound and, if desired, a binder, characterized in that at least one sulphonamide-substituted porphyrin of the formula A, where the porphyrin of the formula (A) may bear further substituents and M represents two hydrogen radicals, a divalent metal atom, divalent metalloxy or a trivalent or tetravalent substituted metal atom, is used as light-absorbent compound.
