O-COORDINATED METAL CHELATES AND THEIR USE IN OPTICAL RECORDING MEDIA HAVING HIGH STORAGE CAPACITY |
摘要 |
The invention relates to novel o ptical recording materials that comprise specific and in some cases novel diketone enamines or metal chelates thereof and that have excellent recording and playback quality especially ata wavelength of 350-500 nm. The invention accordingly relates to an optical recording medium comprising a substrate, a recording layer and optionally a reflecting layer, wherein the recording layer comprises a compound of formula (I), wherein M is hydrogen, aluminium or, preferably, a transition metal, which may in addition be coordinated with one or more further ligands and/or, for balancing out an excess charge, where applicable, may have an electrostatic interaction with one or more further ions inside or outside the coordination sphere, but M in formulae (Ib) and (Ic) is not hydrogen, Q is C-H, N or C-R6, it being possible for the stereochernistry of the C=Q double bond to be either E or Z. For the exact definitions of R1 to R6 reference should be made to the description. Also claimed are the novel compounds, especially tetracoordinated chelates, and a process for the preparation thereof. |
