The present invention relates to new triarylmethane / bis-azo metal complex dye compounds and their use as dyes in optical layers for optical data recording, preferably for optical data recording using a laser with a wavelength from 630 to 670 nm.
The invention further relates to an optical layer comprising said dyes and to a write only read many (WORM) type optical recording medium capable of recording and reproducing information with radiation of red laser, which employs an triarylmethane / bis-azo metal complex type dye in the optical layer.
In particular, the present invention relates to crystal violet / bis-azo metal complex dye compounds and their use as dyes in optical layers for optical data recording
