    摘要： 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.

    摘要： Provided is a process and solvent solution for coating an aza-annulene chromophore containing film directly onto a polycarbonate or polymethylmethacrylate comprising base. In the process, a solution of the chromophore, e.g., phthalocyanine, porphyrin or naphthalocynine, is cast directly onto the polycarbonate or polymethylmethacrylate base, with the solvent used in formulating the solution comprising a C.sub.5 -C.sub.7 cyclic alcohol, or a mixture of solvents including at least one of the aforementioned alcohols. The solvent is then removed, preferably by evaporation, in order to yield a smooth, homogeneous chromophore containing film directly on the polycarbonate or polymethylmethacrylate comprising base. This process is particularly applicable to the manufacture of optical recording media as the particular solvents employed in the process exhibit surprising and unique solvency characteristics with respect to aza-annulene chromophores, and do not attack polycarbonate or polymethylmethacrylate containing bases. The process therefore offers the advantage of being able to manufacture a medium employing a polycarbonate or polymethylmethacrylate substrate without the need for a subbing layer.

    摘要： Provided is an information recording medium, e.g., an optical recording medium, and a method for recording information thereon. The information layer of the recording medium comprises an organo macrocyclic chromophore containing a central hetero atom or two central hydrogen atoms or isotopes of hydrogen, e.g., a naphthalocyanine having silicon as the hetero atom, which chromophore is substituted with at least one substituent conferring film forming properties to the chromophore, e.g., a monomer or oligomeric substituent comprised of acid, amide or ester units. The information layer thereby 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 dye/polymer mixtures is also overcome.

    摘要： Provided is an optical information medium which permits the reading and writing of optical information by actively using polarized light. The optical information medium comprises an information layer containing a compound which undergoes a change upon irradiation with circularly polarized light to provide a new product which is optically active, and which is distinguishable from the original compound in its interaction with polarized light. In a preferred embodiment, the optical medium comprises optical isomers which can be selectively photolyzed by circularly polarized light. While writing must be done using a circularly polarized light source, reading of the recorded information can be accomplished using either circularly polarized light or linearly polarized light.
