EINSATZ VON INFRAROTSENSITIVEN CHROMOPHOREN IN OPTISCHEN AUFZEICHNUNGSTRAEGERN.

摘要

Provided is an optical information recording medium and a method of recording information thereon. The information layer of the recording medium comprises an anthracyanine or phenanthracyanine chromophore compound. In a preferred embodiment, the 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 resulting information layer exhibits strong absorption in the range of from about 780-850 nm. Employing an anthracyanine or phenanthracyanine chromophore substituted with a film forming substituent further offers the advantages of a single component material exhibiting good thermomechanical properties.
