PYRIDINE N-OXIDE BASED AZO DYES AND THEIR METAL COMPLEXES FOR USE IN OPTICAL LAYERS FOR OPTICAL DATA RECORDING. |
摘要 |
<p>The present invention relates to the use of pyridine N-oxide based azo dyes and their metal complexes in optical layers for optical data recording, preferably for optical data recording using a blue laser with a wavelength up to 450 nm or a red laser with a wavelength up to 650 nm. The invention further relates to a write only read many (WORM) type optical recording medium capable of recording and reproducing information with radiation of a blue or red laser, which employs a pyridine N-oxide based azo dye or a respective metal complex in the optical layer.</p> |
