Abstract
Optical recording has been performed successfully by the preirradiation of light upon the precursor of a conducting polymer such as poly(p-phenylene vinylene) and its derivatives and subsequent thermal treatment and washing with water. The effect has been tentatively interpreted in terms of the deterioration of the irradiated area of the precursor film in which polymerization is suppressed. The application of this phenomenon for lithography has been also proposed.
