Abstract
The invention discloses new indolestyryl compounds and their uses for a high-density optical recording medium. The invention uses the new indolestyryl compounds to form the recording layer of a high-density recording medium. The new indolestyryl compounds are easy to prepare and purify, so they are cheaper when comparing to the compounds generally used in high-density optical recording media. The indolestyryl compounds have a maximum absorption for light wavelengths in the range of 500 nanometers to 700 nanometers. The indolestyryl compounds also have high sensitivity and chemical stability toward light and heat. Using the new indolestyryl compounds to form high-density optical recording media can match up with the short-wavelength laser beam for high-density optical recording media and have the advantage of a stable quality.
