摘要： A uniform thin film can be formed simply through coating by using a spin-coating method, and a satisfactory optical property (high refractive index) is obtained by using a dye material (a dye composition containing a mono(aza)methine dye and a basic compound) capable of forming an H-aggregate. The mono(aza)methine dye and the basic compound, which exhibit good solubility, are used as the dye material, and thereby, a solvent that does not corrode a substrate can be employed. Consequently, an optical recording layer composed of a thin film that has formed an H-aggregate is provided, a dye thin film exhibiting a large difference in refractive index between before and after the recording can be used, wherein the decomposition of the dye is an endothermic reaction, and application on a substrate can be performed by a spin-coating method.
