    • 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 a 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-C8heteroaryl 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 CR20R21, O, S or NR22, Q4 is CR16 or N and Q6 is CR17 or N; and R2 and/or R6 are O, S or NR33. 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, G2M1, R1R2, R4, R5, R6, R8, R22 and R23 are as defined in formula (I), M2m+ 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.
    • 因此,本发明涉及一种包括基底,反射层和记录层的光学记录介质,其中记录层包含式(I)化合物或其互变异构体或互变异构体,其中M1是金属阳离子 氧化态+3,其中金属处于氧化态+4的羟基或卤代金属基团,或其中金属处于氧化态+5的氧代金属基团; (III)和(IV)各自独立于另一个(V),(VI)或(VII); (VIII)为(IX),(X),(XI),(XII),(XIII)或(XIV); (XV)是(XVI)或未被取代或被R10,R11,R12和/或R13单取代或多取代的C 2 -C 8杂芳基; Q1是N或CR18,Q2是N或CR19,Q3,Q5和Q7各自独立于另一个CR20R21,O,S或NR22,Q4是CR16或N,Q6是CR17或N; 且R 2和/或R 6为O,S或NR 33。 请参阅其他不太相关的其他取代基的披露。 式(I)化合物是新的,也要求保护的,以及式(II)化合物或其互变异构体或互变异构体,其中R38是卤素,CF3,NO2,CN,COR22,COOR23,SO3R23,NCO或 SCN,G1,G2M1,R1R2,R4,R5,R6,R8,R22和R23如式(I)中所定义,M2m +是具有m个正电荷的阳离子,m是整数1,2或3.光学 记录介质非常适合于DVD±R(658nm),特别是在高记录速度下。
