Optical recording materials writable using blue lasers |
摘要 |
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<SUB>1 </SUB>and G<SUB>2 </SUB>are each independently of the other C(R<SUB>5</SUB>) or N; M<SUB>1 </SUB>is a lanthanide or transition metal of groups 4 to 10; P is a phthalocyanino diradical; and R<SUB>1 </SUB>to R<SUB>5 </SUB>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.
