Abstract

Photoelectrophoretic phenomena have been employed in a new direct color-imaging system. Light-sensitive pigment particles dispersed in highly insulating liquids are subjected simultaneously to strong electric fields and electromagnetic radiant energy. Spectrally selective migration of the particles produces the color image. Absorption characteristics for typical photosensitive pigments are presented. The imaging configuration is described, and the pigment properties required for successful color reproduction are stated.
