ABSTRACT:
Photosensitive cuprous halide-type materials, particularly cuprous chloride and cuprous bromide materials, can be prepared from an anode product material produced from electrolysis of copper in an aqueous acid halide bath. Preferably, the copper electrolysis is carried out in a dilute hydrochloric acid solution. The resulting anode product materials are particularly sensitive in the presence of a polar molecule catalyst such as water or ammonia. In one highly preferred embodiment of this invention the anode product material is treated with the aqueous solution of ammonium salt of a water soluble organic acid (e.g. aqueous solution of ammonium ascorbate); one of the chief advantages of these materials is that they are highly photosensitive when dry and can be developed from a latent image prepared thereon.
