A photoactive ink is prepared by reducing arsenic triselenide to submicron size particles by attrition and subsequently imbedding the particles into polymer latices such as poly-vinylacetate having a particle size of less than 20 microns, by impaction. Well-defined particles completely saturated with arsenic triselenide are formed, These particles are suspended in a suitable electrically insulating liquid to produce a photoactice inks The ink can be utilized by placing it between a pair of electrodes, subjecting it to an electric field and exposing the ink to a pattern of light and shadow, Upon separation of the electrodes, imagewise patterns appear on each surface,
