Abstract : A new grade of zinc oxide was found to have higher photoconductivity than previous samples. The speed of the photoelectropolymerization process was found to increase by a factor of four when using this sample; it is four times faster than Scona Reflex Paper Type C (silver halide photographic paper). Newly acquired photoconductors have been tested in the sandwich arrangement used in the photoelectrolytic imaging system. One variety of cadmium sulfide (Sylvania PC-103) when exposed in conjuction with a monomer layer on a aluminum showed a photographic speed five times faster than that of Scona Reflex Paper Type C. A cadmium sulfoselenide photoconductor was characterized by extremely fast photoresponse. Each of these photoconductors differs from zinc oxide in that it transmits photocurrent in either direction through the layer. The concentration range was determined for ferrous ammonium sulfate in the monomer coating of the positive imaging system. The sensitivity of the positive imaging system was found to be 50% less than that of the negative working process. Gelatin has been insolubilized by electrochemical means. Image-wise resists were produced in sandwich arrangements consisting of zinc oxide and gelatin coatings containing various electrochemical catalysts.
