OPTICAL DATA CARRIER THAT CONTAINS A CYANINE DYE AS THE LIGHT-ABSORBING COMPOUND IN THE INFORMATION LAYER

摘要

The invention relates to an optical data carrier that contains a preferably transparent substrate that is optionally already coated with one or more reflective layers, onto whose surface an information layer which can be written on with light, optionally one or more reflective layers and optionally a protective layer or a further substrate or a cover layer are applied. Said optical data carrier can be written on and read with blue, red or infrared light, preferably laser light, and the information layer comprises a light-absorbing compound and optionally a binder. The inventive data carrier is further characterized in that at least one cyanine dye is used as the light-absorbing compound.
