ABSTRACT:
The invention relates to phthalocyanines and metal complexes thereof with divalent metals or divalent oxo metals, which contain at least one phosphorus-containing substituent bonded to the peripheral carbon skeleton via the phosphorus atom.
The compounds preferably conform to the general structural formula (G).sub.k -A-(Q).sub.l, in which A is a phthalocyanine or metal complex thereof with a divalent metal or a divalent oxo metal, G is a phosphorus-containing substituent, Q is a further substituent as defined below, the index k is a number from 1 to 16, and l, independently thereof, is 0 or a number from 1 to 15, with the proviso that the sum of k and l is a number less than or equal to 16.
The invention also relates to a material for the optical recording and storage of information, in which at least one storage layer (2) of a novel phthalocyanine compound or a metal complex thereof has been applied to a transparent, dielectric carrier material (1).
