Photographic polymeric images and process for producing same

Claim 1

A PROCESS OF PRODUCING A POLYMERIC PHOTOGRAPHIC IMAGE WHICH COMPRISES EXPOSING TO A PATTERN OF ACTINIC RADIATION IN THE ULTRAVIOLET TO VISIBLE REGION OF THE SPECTRUM A PHOTOGRAPHIC ELEMENT CARRYING ON A SUITABLE SUPPORT A LIGHT SENSITIVE LAYER COMPRISING A MONOMER CONTAINING A TERMINAL CH2=C=GROUP AND A LIGHT SENSITIVE FERRIC SALT OF AN ORGANIC ACID DISPERSED IN A PHOTOGRAPHIC COLLOIDAL HYDROPHILIC CARRIER MATERIAL, TO FORM BY SAID EXPOSING IMAGEWISE QUANTITIES OF EXPOSURE ACTIVATED IRON SALT; IN SAID LAYER CONTACTING THE EXPOSED MATERIAL WITH A SOLUTION OF COMPOUND CAPABLE OF SUPPLYING POSITIVE HALOGEN, SAID COMPOUND BEING SELECTED FROM THE GROUP CONSISTING OF ALKALI METAL HYPOHALITES, N-BROMOSUCCINIMIDE, THE SODIUM SALT OF N-CHLORO-P-TOLUENESULFONAMIDE, N,NDICHLORODIMETHYLHYDANTOIN, N - CHLOROSUCCINIMIDE AND MONOCHLOROUREA, WHEREBY POLYMERIZATION OCCURS IN PROPORTION TO THE AMOUNT OF ACTIVATED IRON SALT; REMOVING BY WASHING ANY RISIDUAL UNPOLYMERIZED MONOMER THEREBY LEAVING A POLYMERIZABLE PHOTOGRAPHIC IMAGE THE DENSITY OF WHICH CORRESPONDS TO THE INTENSITY OF THE EXPOSING RADIATION PATTERN.
