Abstract
Abstract AN ALKYLENE OXIDE POLYMER, SUCH AS POLYETHYLENE GLYCOL OLEYL ETHER, AND/OR A MERCAPTOTETRAZOLE DERIVATIVE, SUCH AS 1-PHENYL-5-MERCAPTOTETRAZOLE, IN COMBINATION WITH A GELATINO SILVER HALIDE EMULSION, A HEAVY METAL SALT OXIDIZING AGENT AND A REDUCING AGENT, SUCH AS A BIS-NAPHTHOL REDUCING AGENT, IN A PHOTOSENSITIVE AND THERMOSENSITIVE ELEMENT SUITABLE FOR DRY PROCESSING WITH HEAT, PROVIDES INCREASED PHOTOSENSITIVITY. A COMBINATION OF A BISB-NAPHTHOL REDUCING AGENT, A GELATINO SILVER HALIDE EMULSION, AN ALKYLENE OXIDE POLYMER AND/OR A MERCAPTOTRAZOLE DERIVATIVE IN CONJUNCTION WITH A STABLE SOURCE OF SILVER FOR PHYSICAL DEVELOPMENT IS USEFUL IN MPHOTOSENSITIVE ELEMENTS FOR DRY PROCESSING WITH HEAT. THE ELEMENT CAN CONTAIN A SENSITIZING DYE AND AN ACTIVATOR-TONING AGENT. A STABLE DEVELOPED IMAGE IS PROVIDED BY HEATING THE ELEMENT. OTHER SUITABLE PHOTOSENSITIVE METAL SALTS CAN BE USED IN THE PHOTOSENSITIVE ELEMENT.
