ANTIPYRINE BASED AZO METAL COMPLEX DYES AND THEIR USE IN OPTICAL LAYERS FOR OPTICAL DATA RECORDING.

摘要

The present invention relates to antipyrine based azo metal complex dyes andtheir use in optical layers for optical data recording, preferably for opticaldata recording using a laser with a wavelength up to 450 nm. The invention furtherrelates to a write only read many (WORM) type optical data recording medium capableof recording and reproducing information with radiation of blue laser, whichemploys an antipyrine based azo metal complex dye in the optical layer.
