| 摘要 |
This invention relates to an optical recording medium, comprising a substrate, a recording layer and a reflecting layer, where the recording layer comprises at least one dye of formula wherein A1 and A2 are each independently of the other C(CH3)2, O, S, Se, or CH=CH which is unsubstituted or substituted by C1-C5alkyl or benzyl; M1 and M2 are each independently of the other Cr3+ or Co3+; L1 and L1' are each independently of the other a ligand of formula L2 and L2' are each independently of the other and independently of L1 and L1' a ligand of formula (II), (III) or m is a number from 0.2 to 1.0; and n, depending on m, is a number from 0.0 to 0.8, so that the sum of m and n equals 1.0; p and q are each independently of the other 0 or 1; and Q is CR15, CR15-CR16=CR17 or CR15-CR16=CR17-CR18=CR19. This invention also claims the dyes of formula (I) themselves as well as a process for optically recording, storing or reproducing information using a recording medium of this invention, recording or reproduction preferably being carried out at the wavelength range from 600 to 800 nm.
