摘要:
A recordable optical recording medium is provided enabling the light transmission layer to be a single layer, the inhibition of peeling of the recording layer even when stored in high-temperature/high-moisture conditions, and the reduction of degradation of the recording/reproduction characteristics. A recordable optical recording medium provided with a substrate, and, on the substrate in the following order, a reflective layer, a recording layer, a protective layer, and a light transmission layer. The optical recording medium has the recording layer formed thereon using an organic dye obtained by adding a highly waterproof, low hydrophilic organic dye to a triazole-based azo metal complex dye.
摘要:
An aspect of the present invention relates to an optical information recording medium comprising a recording layer on a surface of a support, wherein the surface of the support has pregrooves with a track pitch ranging from 50 to 500 nm, the recording layer comprises an azo metal complex dye being a complex of six azo dyes and seven transition metal ions. A further aspect of the present invention relates to a method of recording information onto the optical information recording medium and a novel azo metal complex dye.
摘要:
The invention relates to an ink composition containing a multimetallic oligomeric or polymeric azo colorant wherein the colorant is derived from the polymerization reaction of a polyvalent metal cation with a dimeric tridentate ligand containing a coordinating azo group.
