Photothermographic elements containing bis-beta-naphthols
Abstract
Abstract A REDUCING AGENT, SUCH AS A BIS-RAPHTHOL, IN COMBINATTION WITH AN ACTIVATOR-TONING AGENT, SUCH AS A CYCLIC IMIDE, IN A PHOTOSENSITIVE AND THERMOSENSITIVE ELEMENT SUITABLE FOR DRY PROCESING WITH HEAT, PROVIDES IMPROVED PRE-PROCESSING INCUBATION STABILITY, INCREASED SENSITIVITY INCLUDING REDUCED EXPOSURE AND PROCESSING TIME, MORE NEUTRAL MAXIMUM DENSITY AREAS AND GREATER IMAGE STABILITY. A COMBINATION OF A BIS-NAPHTHOL REDUCING AGENT AND A CYCLICIMIDE ACTIVATOR-TONING AGENT IN CONJUNCTION WITH A STABLE SOURCE OF SILVER FOR PHYSICAL DEVELOPMENT ARE USEFUL IN PHOTOSENSITIVE ELEMENTS FOR DRY PROCESSING. THE ELEMENT CAN CONTAIN A SENSITIZING DYE AND A STABLE, DEVELOPED IMAGE CAN BE PROVIDED BY HEATING THE ELEMENT AFTER EXPOSURE. THE PHOTOSENSITIVE COMPONENT CAN BE PHOTOGRAPHIC SILVER HALIDE, OR OTHER SUITABLE PHOTOSENSITIVE METAL SALTS.
