ABSTRACT:
A novel naphthalocyanine based compound having Si atom as a central metal and groups selected from ##STR1## CN, and --CH.dbd.CH.sub.2 which is bonded to said Si atom via a specific hydrocarbon group, by which solubility in an organic solvent, compatibility with a polymeric substance and durability against an infrared ray are improved. The compound may be incorporated into a polymeric substance layer to form a recording layer of an optical recording medium.
