ABSTRACT:
An optical recording medium contains at least one squarylium- or croconium-base dye of formulae [I] or [II], and a carboxylic acid-base metallic complex: ##STR1## where A.sym. is a cationic bivalent organic residue and B is a monovalent organic residue. The optical recording medium has an absorption band for light in the long wavelength region and is superior in stability against heat and light.
