Compositions comprising monosubstituted squaric acid metal complex dyes and merocycanine based dyes and their use in optical layers for optical data recording |
摘要 |
The present invention relates to compositions monosubstituted squaric acid metal complex dyes and merocycanine based 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 compositions comprising monosubstituted squaric acid metal complex dyes and merocycanine based dyes in the optical layer.
