摘要:
The invention discloses new benzoindole styryl compounds and its use for a high-density optical recording medium. The invention uses the dyes of the new benzoindole styryl compounds to form the recording layer of high-density recording media. The new benzoindole styryl 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 benzoindole styryl compounds has a maximum absorption for the light wavelength in the range of 500 nanometers to 700 nanometers. The benzoindole styryl compounds also have high sensitivity and chemical stability for light and heat. Using the new benzoindole styryl compounds to form a high-density optical recording medium can match up with the short-wavelength laser beam for high-density optical recording media and have the advantage of a stable quality.
