Abstract

A trial full-color rewritable film has been prepared by mixing fulgide derivatives as three primary-coloring dyes in a polymer, giving practically colorless or black form upon irradiation with white light or UV light. A good color image was obtained by a simple, one-shot irradiation with white light above the positive-color mask attached on the black film. The image could be erased and rewritten with another positive mask though degraded after many erase–write cycles.
