Abstract (en)
[origin: WO0225648A1] The invention relates to an optical data carrier containing a preferably transparent substrate which is optionally coated with one or more reflecting layers. A light-inscribable information layer and optionally one or more reflecting layers and optionally a protection layer and another substrate or a covering layer are applied to the surface of said substrate. Said optical data carrier can be inscribed and read with blue light, preferably laser light. The information layer comprises a light absorbing compound and optionally a binding agent. The inventive optical data carrier is characterised in that at least one phthalocyanine colouring agent is used as a light absorbing compound.
