Claim:
A phthalocyanine compound of Formula I wherein at least the eight groups represented by R 1 , R 4 , R 5 , R 8 , R 9 , R 12 , R 13 & R 16 which groups are identical are —X-J wherein J is selected from the group consisting of C 1-6 -alkyl; C 2-6 -alkenyl; C 4-8 -cycloalkyl each being optionally substituted by a group selected from the group consisting of C 1-4 -alkoxy, C 1-4 -alkylthio, C 6-12 -aryl, C 6-12 -arylthio, C 1-4 -alkylsulphonyl, C 1-4 -alkylsulphonylamino, C 1-4 -alkylsulphoxide, amino, mono- and di-C 1-4 -alkylamino, halogen, nitro, cyano and hydroxycarbonyl (—COOH), hydroxysulphonyl (—SO 3 H) or dihydroxyphosphonyl (—PO 3 H 2 ) or C 1-4 -alkyl esters thereof and from C 6-12 -aryl optionally substituted by a group selected from the group consisting of C 1-3 -alkyl, C 1-3 -alkoxy, C 1-3 -alkylthio, C 1-3 -alkylsulphonyl, C 1-3 -alkylsulphonylamino, C 1-4 -alkylsulphoxide, amino, mono- and di-C 1-3 -alkylamino, halogen, nitro, cyano and hydroxycarbonyl, hydroxysulphonyl or dihydroxyphosphonyl, hydroxycarbonyl-C 1-3 -alkyl, hydroxysulphonyl-C 1-3 -alkyl, dihydroxyphosphonyl-C 1-3 -alkyl or C 1-3 -alkyl esters thereof; M is an oxymetal group selected from the group consisting of VO, TiO and MoO; X is S, Se, Te or NT; T is H, alkyl or phenyl, or T & J, together with the N atom to which they are attached, form an aliphatic or aromatic ring provided this N atom is not positively charged; provided where J is aryl, T is not aryl; and wherein each of R 2 , R 3 , R 6 , R 7 , R 10 , R 11 , R 14 and R 15 is H with the proviso that the compound is not octa-3,6-(phenylthio)VOPc, octa-3,6-(methylthio)TiOPc or octa-3,6-(ethylthio)VOPc.
