Abstract:
A process for the manufacture of an optical recording medium having at least one recording layer, comprising the steps ofa) incorporating a metallocenyl-phthalocyanine represented by formula I whereinM1 is a divalent metal, an oxometal group, halogenometal group or hydroxymetal group, or two hydrogen atoms, X is halogen Y1 is â€”OR1, â€”OOCâ€”R2, â€”NHR1, â€”N(R1)R2, Y2 is â€”SR1, R3 is R6 and R7 are each independently of the other hydrogen, halogen, C1-C4alkyl, C1-C4alkoxy, amino-C1-C4alkyl, diarylphosphine, or phosphorus-containing C1-C4alkyl, M2 is a transition metal cation, x may be a rational number from 0 to 8 y1 and y2 may be each independently of the other a rational number from 0 to 6 z may be a number from 1 to 4, wherein (x+y1+y2+z) is &lE;16, and wherein R1 and R2 may be each independently of the other C1-C20alkyl which is unsubstituted or substituted by halogen, hydroxy, C1-C20alkoxy, C1-C20alkylamino or C2-C20dialkylamino and which may be interrupted by â€”Oâ€”, â€”Sâ€”, â€”NHâ€” or â€”NR10â€”, wherein R10 may be C1-C6alkyl, C5-C20cycloalkyl, C2-C20alkenyl, C5-C12cycloalkenyl, C2-C20alkynyl, C6-C18aryl or C7-C18aralkyl, and wherein one or two ligands may optionally be bound to the divalent metal atom, the oxometal group, halogenometal group or hydroxymetal group, and E is composed of a chain of at least two members selected from the group consisting of â€”CH2â€”, â€”C(&boxH;O)â€”, â€”CH(C1-C4alkyl)â€”, â€”C(C1-C4alkyl)2â€”, â€”NHâ€”, â€”Sâ€”, â€”Oâ€” and â€”CH&boxH;CHâ€” into said record layer, wherein the substrate is a homo- or copolymeric plastic.
