Optical recording material |
摘要 |
The present invention relates to a recording member having an inherent optical absorption wavelength range and a property of changing optical absorption spectral characteristics before and after the absorption of light to record informations by absorbing a light within the optical absorption wavelength range. In order to shift the wavelength range of this optical absorption spectrum toward longer wavelengths, at least one kind of substituents having a pi electron system, an electron donative property or an electron acceptive property is used as a substituent of a molecule constructing the recording member in an optical recording material. Such an optical recording material can be used in memories in the computer system and the like.
