摘要
The present invention relates to new monosubstituted squaric acid metal complex 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 recording medium capable of recording and reproducing information with radiation of blue laser, which employs a monosubstituted squaric acid metal complex dye in the optical layer.
