METAL COMPLEXES AS LIGHT-ABSORBING COMPOUNDS IN THE INFORMATION LAYER OF OPTICAL DATA CARRIERS

摘要

Disclosed are novel metal complexes for an optical data carrier comprising a preferably transparent substrate which is optionally coated with one or several reflection layers, and to the surface of which an information layer that is writable by means of light, one or several optional refection layers, and an optional protective layer or another substrate or a covering layer are applied. Said data carrier is writable and readable by means of blue light or red light, preferably laser light. The information layer is provided with a light-absorbing compound and an optional bonding agent. The invention is characterized by the fact that at least said metal complex is used as a light-absorbing compound.
