Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A recordable optical recording medium, comprising a substrate on which at least a reflective layer, a recording layer and a light transmission layer are provided, characterized in that the recording layer is formed by adding a low hydrophilic and highly waterproof organic dye to a triazole-based azo metal complex dye represented by the following general formula (1):…
