The present invention relates to o,p-dialkoxy-phenyl-azometal complex dyes and their use in optical layers for optical data recording, preferably for optical data recording using a laser with a wavelength up to 450 nm. The invention further relates to a write once read many (WORM) type optical data recording medium capable of recording and reproducing information with radiation of blue laser, which employs an o,p-dialkoxy-phenyl-azometal complex dye in the optical layer. |
