The azo metal complex dye which designates antipyrine as the base and these uses in the optical layer for optical data logging

摘要

As for this invention, the azo metal complex dye and the one for optical data logging which designate antipyrine as the base, desirably, in the optical layer for the optical data logging which uses the laser which possesses the wave length to 450nm, it regards the use of these dyes. As for this invention, furthermore, using blue laser radiation, it is possible, to record information and to play back, the azo metal complex dye which designates antipyrine as the base in optical layer is used, raitoonriridomeni (WORM) it regards the optical data logging medium of type.
