ABSTRACT:
An optical information recording medium is disclosed, which comprises a substrate and an organic recording layer formed thereon comprising a polymethine dye and a dithiolate transition metal complex compound having formula (I): ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 each independently represent hydrogen, a halogen, an alkyl group having 1 to 6 carbon atoms, or a perfluoroalkyl group having 1 to 6 carbon atoms; R.sup.4 and R.sup.5 each independently represent hydrogen, an alkyl group having 1 to 6 carbon atoms, an aryl group or a cyano group, which may form a heterocyclic ring; X represents a cation; M represents a transition metal; n is an integer of 0 to 2, which represents the valence number of the transition metal; and m represents the number of cations, which is an integer of 0 to 2, corresponding to the valence number of the transition metal. Furthermore, novel dithiolate nickel complex compounds for use in the optical information recording medium are disclosed.
