Abstract (en)

[origin: WO03019548A1] Optical data support, comprising a preferably transparent substrate, optionally pre-coated with one or several reflective layers, on the surface of which an information layer, which may be written by light, optionally one or several reflective layers and optionally a protective layer, or a further substrate or a cover layer are applied, which can be written and read with blue light, preferably laser light, or infra-red light, preferably laser light. The information layer contains a light-absorbing compound and optionally a binding agent, characterised in that at least one phthalocyanine of formula (I) is used as light-absorbing compound, where Me = an axially disubstituted metal atom of the group Si, Ge and Sn, Pc = an unsubstituted phthalocyanine and X1 and X2 independently = halogen, in particular, fluorine, chlorine or bromine.
