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.
该发明涉及一种新型光学记录材料,包括具有特定的、在某些情况下是新颖的二酮偶氮或其金属螯合物的化合物,并且在波长为350-500纳米时具有出色的记录和播放质量。因此,该发明涉及一种光学记录介质,包括基板、记录层和可选的反射层,其中记录层包括式(I)的化合物,其中M是氢、铝或者更好地是过渡金属,可能还可以与一个或多个进一步的配体配位,并/或者,为了平衡过剩电荷,在适当的情况下,可能与内部或外部的一个或多个进一步的离子发生静电相互作用,但是在式(Ib)和(Ic)中的M不是氢,Q是C-H、N或C-R6,C=Q双键的立体化学可能是E或Z。有关R1到R6的确切定义,请参考说明。还声明了这些新型化合物,特别是四配位的螯合物,以及其制备方法。
