High-Capacity Optical Storage Media
摘要:
The invention relates to an optical recording medium comprising a substrate, a reflecting layer and a recording layer, wherein the recording layer comprises a compound of formula preferably a compound of formula or a mesomeric or tautomeric form thereof, wherein Ah+ is an organic cation having h quaternary ammonium or phosphonium groups; Q1 is N or CR15, Q2 is N or CR16, Q3, Q5 and Q7 are each independently of the other CR17R18, O, S or NR19, Q4 is CR13 or N and Q6 is CR14 or N; and one of R1 and R3 is OR17, OR20, SR17, SR20, NR17R18, NR18R20 or NR20R21, and the other of R1 and R3 is O−, S− or N−R22. The compounds of formula (I) and (II) are novel and also claimed, as well as mixtures thereof with metal complexes. The optical recording media are remarkably suitable for DVD±R (658 nm), especially at high recording speeds.
