Optical data carriers containing Co-phthalocyanine complex in light writable information layer

摘要

The present invention relates to a singly recordable optical data medium using Co-phthalocyanine complexes of the formula (I) In which the groups are defined herein, as light-absorbing compounds in the information layer of optical data media, in which information layer is recordable using light, particularly for CD-R, and the application of the above-mentioned compounds to a polymer substrate, particularly polycarbonate, by spin coating.
