Optical recording medium

摘要

An object of the present invention is to provide a recordable optical recording medium whose characteristics do not deteriorate when recording is conducted in a high-temperature environment. The present invention provides a recordable optical recording medium comprising a substrate as well as at least a reflection layer, recording layer and light transmission layer provided on the substrate, wherein the recording layer of said optical recording medium contains (a) an azo metal complex dye and (b) ionic organic compound containing a heteroaromatic quaternary ammonium ion.

1. An optical recording medium comprising a substrate as well as at least a reflection layer, recording layer, and light transmission layer provided on the substrate, wherein a dye included in the recording layer of said optical recording medium contains (a) an azo metal complex dye and (b) an ionic organic compound containing a heteroaromatic quaternary ammonium ion, wherein the heteroaromatic quaternary ammonium ion in the ionic organic compound (b) is a quaternary ammonium ion produced by quaternarizing nitrogen in a nitrogen-containing heteroaromatic ring compound using an alkyl group or aryl group.
