ABSTRACT:
Provided is an optical information medium containing an information layer comprised of a 1-phenyl substituted naphthalocyanine. Also provided is a method for easily synthesizing the naphthalocyanine chromophore used in the information layer. The use of such naphthalocyanine chromophores in the information layer of an optical information medium provides one with many advantages. In the manufacture of the medium, these advantages arise due to the increased solubility exhibited by the chromophore in conventional organic solvents. As well, the chromophores exhibit excellent and unique optical properties useful in the recording of optical information.
