Media for optical information storage comprising an organic macrocyclic chromophore substituted with a film conferring organic substitutent

Abstract From the Canadian patent

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 …
