| 摘要 | The invention relates to novel metal complexes for optical data carriers, whereby the latter is preferably a transparent substrate which is, optionally already covered with one or several reflective layers. A light-inscriptible information layer is disposed on the surface thereof, in addition to, optionally, one or several reflective layers and, optionally, a protective layer or another substrate or a covering layer which is inscriptible or readable with blue, red or infrared light, preferably laser light. The information layer contains a light-absorbing compound and, optionally, a binding agent. The invention is characterised in that the at least said metal complex is used as a light-absorbing compound. | ||||||
