The invention accordingly 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 (I) or a mesomeric or tautomeric form thereof, wherein M1 is a metal cation in the oxidation state +3, a hydroxy or halogeno metal group wherein the metal is in the oxidation state +4, or an oxo metal group wherein the metal is in the oxidation state +5; (III) and (IV) are each independently of the other (V), (VI) or (VII); (VIII) is (IX), (X), (XI), (XII), (XIII) or (XIV); (XV) is (XVI) or C2-C8 heteroaryl unsubstituted or mono- or poly-substituted by R10, R11, R12 and/or R13; Q1 is N or CR18 , Q2 is N or CR19 , Q3, Q5 and Q7 are each independently of the other CR 20 R 21, O, S or NR22 , Q4 is CR16 or N and Q6 is CR 17 or N ; and R2 and/or R 6 are O, S or NR 33. Please see the disclosure for the other substituents which are less relevant. The compounds of formula (I) are novel and also claimed, as well as the compound of formula (II), or a mesomer or tautomer thereof, wherein R38 is halogen, CF3, NO2, CN, COR22, COOR23 , SO3R23, NCO or SCN, G1, G 2, M1, R1, R2, R4, R5, R6, R8, R22 and R23 are as defined in formula (I), M 2m+ is a cation with m positive charges, and m is an integer 1, 2 or 3. The optical recording media are remarkably suitable for DVD±R (658 nm), especially at high recording speeds.
该发明涉及一种光学记录介质,包括基板、反射层和记录层,其中所述记录层包括式(I)的化合物或其互变异构体或互变构异体,其中M1是+3氧化态的金属阳离子,氢氧基或卤金属基,其中金属处于+4氧化态,或氧金属基,其中金属处于+5氧化态;(III)和(IV)各自独立于其他(V)、(VI)或(VII);(VIII)是(IX)、(X)、(XI)、(XII)、(XIII)或(XIV);(XV)是( XVI)或未经R10、R11、R12和/或R13取代的C2-C8杂环芳基;Q1是N或CR18,Q2是N或CR19,Q3、Q5和Q7各自独立于其他CR20R21、O、S或NR22,Q4是CR16或N,Q6是CR17或N;而R2和/或R6是O、S或NR33。请参阅其他不太相关的取代基的披露。式(I)的化合物是新颖的,并且也被要求,以及式(II)的化合物,或其互变异构体或互变构异体,其中R38是卤素、CF3、NO2、CN、COR22、COOR23、SO3R23、NCO或SCN,G1、G2、M1、R1、R2、R4、R5、R6、R8、R22和R23如式(I)中定义,M2m+是具有m正电荷的阳离子,m是整数1、2或3。这些光学记录介质非常适用于DVD±R(658纳米),尤其在高速记录时。
