Abstract:
The invention relates to an optical recording medium comprising a substrate, a recording layer and optionally one or more reflecting layers, wherein the recording layer comprises a compound of formula (I) or a tautomeric or mesomeric form thereof, wherein G 1 and G 2 are each independently of the other C(R 5 ) or N; M 1 is a lanthanide or transition metal of groups 4 to 10; P is a phthalocyanino diradical; and R 1 to R 5 are substituents as defined in the description and the claims. Recording and playback are effected especially at a wavelength of from 350 to 500 nm, for example using a blue laser. The recording and playback quality is excellent and allows a high storage density.
