An optical recording material comprising at least one compound represented by the general formula (I). (I) wherein R1 and R2 independently represent a hydrogen atom, a hydroxy group, a halogen atom, a nitro group, a cyano group, an organic group having 1 to 30 carbon atoms, or a group represented by the general formula (II), (II') or (III), or R1 and R2 may together form a cyclic structure; X1 represents-CR3R4-or-NH-; Y1 represents an organic group having 1 to 30 carbon atoms or a substituent represented by the general formula (II), (II') or (III); R3 and R4 independently represent a hydrogen atom, an organic group having 1 to 30 carbon atoms, or a substituent represented by the general formula (II), (II') or (III), provided that R3 represents a hydrogen atom, an organic group having 1 to 30 carbon atoms, or a group represented by the general formula (II), (II') or (III) when Y1 represents a group represented by the general formula (III), and R3 represents a group represented by the general formula (II), (II') or (III) when Y1 represents an organic group having 1 to 30 carbon atoms or a group represented by the general formula (II) or (II'); M represents Fe, Co, Ni, Ti, Cu, Zn, Zr, Cr, Mo, Os, Mn, Ru, Sn, Pd, Rh, Pt or Ir; Anq- represents an anion having a valency of q; p represents a factor that enables to keep the charge neutral; and q represents a number of 1 or 2. |
