ABSTRACT:
An optical recording medium is described, having suitable recording characteristics over a wide range of recording linear speed and fitting with recording/reproduction apparatuses of CD-R specifications. The optical recording medium includes a substrate having at least a light absorbing layer thereon, which is mainly composed of three phthalocyanine compounds (I), (II) and (III). Each of the phthalocyanine compounds (I) and (II) has a thermal decomposition temperature of from 200° C. to 300° C., and has a different light absorption ability against light having a wavelength of 780 nm. The phthalocyanine compound (III) has a thermal decomposition temperature of from 300° C. to 350° C.
