    • Described is an optical recording medium comprising at least one of naphtholactam compounds represented by the specific formulas. The optical recording medium has absorption at the long wavelength side, can make a record with high sensitivity even when a long wavelength oscillation laser such as a semiconductor layer is used, and can obtain a high C/N ratio because of the capability of forming pits with good shapes. It is also possible to provide an optical recording medium which can be readily prepared by coating, has good stability to heat, and has superior storage stability with less reproduction deterioration.
    • 描述了包含由具体式表示的萘酚内酰胺化合物中的至少一种的光学记录介质。 光学记录介质在长波长侧具有吸收,即使使用诸如半导体层的长波长振荡激光器也能够以高灵敏度进行记录,并且由于形成凹坑的能力可以获得高的C / N比 具有良好的形状。 也可以提供一种可以容易地通过涂布制备的,具有良好的耐热稳定性的光学记录介质,并且具有优异的储存稳定性和较少的再现性劣化。
