摘要：
The present invention relates to the use of 3-hydroxy-cyclohex-2-enone azo based dyes and/or of azo metal complex dyes made thereof, and to compositions comprising 3-hydroxy-cyclohex-2-enone azo based dyes and anionic azo metal complex dyes with cationic basic yellow dyes 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 a 3-hydroxy-cyclohex-2-enone azo based dye and/or an azo metal complex dye made thereof, or a composition comprising a 3-hydroxy-cyclohex-2-enone azo based dye and a anionic azo metal complex dye with a cationic basic yellow dye in the optical layer.
