Title:
光データキャリアの情報層における吸光性化合物としてのスクアリリウム色素
Document Type and Number:
Japanese Patent JP2005520835
Kind Code:
A
Abstract:
Novel squarylium compounds for optical data carriers have been found. The latter comprise a preferably transparent substrate to whose surface a light-writable information layer, if desired one or more reflection layers and a further substrate or a protective layer have been applied and can be written on and read by means of red light, preferably laser light, where the information layer comprises a light-absorbent compound and, if desired, a binder. They are characterized in that at least the said squarylium compounds are used as light-absorbent compound.
