BASIC YELLOW DYES AS A DYE COMPONENT FOR OPTICAL RECORDING MEDIA

摘要

The present invention relates to the use of Basic Yellow dyes as dye component for optical data recording media. In a preferred aspect the present invention relates to Basic Yellow dyes together with a metalazo complex dye as dye components for optical data recording media. In a more preferred aspect, the invention relates to a write once read many (WORM) type optical data recording medium capable of recording and reproducing information with radiation of blue laser of preferably 405 nm, which employs a Basic Yellow dye together with a metalazo complex dye and a further recording dye in the optical layer.
