ABSTRACT:
The invention relates to a write-once optical data carrier in which organic and/or inorganic light-absorbing compounds are used as the information layer, especially for high-density optical data carriers which function with a blue laser in the wavelength range of 360-460 nm. The invention also relates to the application of the above-mentioned light-absorbing compound to a suitable substrate (especially polycarbonate), e.g., by spin coating.
