Abstract

A spectrally sensitised anthraquinone pigment (I) with at least one, pref. 2 acylamino gp(s). in the alpha-position is used in a photoelectrophoretic copying process involving exposure of a suspension of a pigment, which is light-sensitive in an electric field, in an insulating liquid to an electric field between 2 electrodes and selectively to actinic light at the same time, so that a pigment image is formed on at least one of the electrodes by transfer of pigment particles. Used for single and multi-colour copying. (I) gives good results and extends the range of pigments suitable for this process.
