Abstract
Disclosed are electrically photosensitive polymers in which recurring units contain vinylene-1,4-phenylene-imino-1,4-phenylene-vinylenearylene groups included in the polymer backbone. In one embodiment, the disclosed polymers are employed as the principal electrically photosensitive constituent in migration imaging dispersions and elements. In another embodiment, the polymers are employed as sensitizers for electrically photosensitive colorants having spectral absorption peaks in the 400-500 nm wavelength region of the spectrum. The polymers are employed in migration imaging dispersions and elements.
