Provided is an optical data storage medium comprising a chromophore/polymer composition information layer, wherein the chromophore is chemically bound or coordinated with the polymer. The chromophore is an organo macrocyclic chromophore containing a constituent metal atom, and preferably a central metal atom, with the chromophore being coordinated to the polymer through the metal atom. As a result, the chromophore/polymer material has excellent film-forming properties so that the medium can be readily and efficiently manufactured. As well, the resulting information layer offers excellent thermomechanical properties and exhibits excellent absorption properties, all in a single component material. By utilizing a single component material, the problem of dye/polymer phase separation frequently encountered in conventional dye/polymer mixtures is also overcome. |
