Abstract
The present invention provides novel organic compounds, which absorb the light in the ultra violet and the infrared regions, have improved light tolerance and solubility in solvents, and have thermal tolerance suitable for uses to which the organic compounds are applied, and provides uses of the same. The above objects are solved by providing indolenine compounds and methine dyes, which have a bis-indolenine skeleton composed of two indolenine rings linked together at their respective C-3 positions via a divalent linking group, and by providing optical recording media containing the methine dyes.
