摘要:
The invention relates to an optical data carrier having a preferably transparent substrate that has optionally previously been coated with one or more reflection layers and to the surface of which has been applied a light-writeable information layer, optionally one or more reflection layers, and optionally a protective layer or a further substrate or a covering layer, such that the optical data carrier can be written on or read by means of blue light (preferably laser light having a specified wavelength) or by means of infrared light (preferably laser light having a specified wavelength), wherein the information layer contains (i) light-absorbent phthalocyanine dyes of the formula (I) where Me is a doubly axially substituted Si, Ge, and Sn atom, Pc is an unsubstituted phthalocyanine, and X1 and X2 are each independently halogen, and (ii) optionally, a binder.
