Optical data carrier comprising a merocyanine dye as light-absorbent compound in the information layer

摘要：

Optical data carrier comprising a preferably transparent substrate which may, if desired, have previously been coated with one or more reflection layers and to whose surface a light-writeable information layer, if desired one or more reflection layers and if desired a protective layer or a further substrate or a covering layer have been applied, which can be written on or read by means of blue, red or infrared light, preferably laser light, where the information layer comprises a light-absorbent compound and, if desired, a binder, characterized in that at least one merocyanine dye is used as light-absorbent compound.

摘要（中）：

光学数据载体，其包括优选透明的基底，如果需要，其可以预先涂覆有一个或多个反射层，并且如果需要，其表面可光可写信息层一个或多个反射层，如果需要，保护层或已经施加了另外的衬底或覆盖层，其可以通过蓝色，红色或红外光（优选激光）写入或读取，其中信息层包含吸光性化合物和如果需要的话粘合剂，其特征在于因为使用至少一种部花青染料作为吸光性化合物。
