The invention relates to an optical data medium containing a preferably transparent substrate that is optionally already coated with one or more reflective layers and on the surface of which have been applied:
(1) an information layer that can be recorded on using light, wherein the information layer contains at least one phthalocyanine light-absorbing compound and optionally a binder,
(2) optionally one or more reflective layers, and
(3) optionally a protective layer or a further substrate or a covering layer
wherein the optical data medium can be recorded on and read using blue light, preferably laser light.
本发明涉及一种光学数据介质,该介质包含一个最好是透明的基底,该基底可选地已经涂有一层或多层反射层,并在其表面涂有以下涂层:
(1) 可以用光记录的信息层,其中信息层含有至少一种
酞菁光吸收化合物和粘合剂、
(2) 可选的一个或多个反射层,以及
(3) 可选的保护层或进一步的基底或覆盖层
