摘要:
Dry stabilization of a silver halide photographic material is obtained by heating the silver halide photographic material to a temperature of at least 80.degree.C. in the presence of an organic iodine-containing compound, such as monoiodoacetic acid, isopropyl iodide, or iodocyclohexane. Preferably, the heating is carried out after the formation of an image on the material. The organic iodine-containing compound can be added to the silver halide emulsion in the molten state during the preparation of the emulsion. This method is especially effective when applied to silver halide photographic materials which contain silver halide grains at least 50 mol% of which consists of silver bromide.
摘要:
A stable positive image having high contrast is formed in a dry system without the necessity of heat treatment by subjecting a light-developable silver halide light-sensitive material having a layer of silver halide grains having occuluded therein bismuth ions and containing a mercaptan compound to an intense imagewise exposure in a short period of time and then subjecting the light sensitive material to an overall uniform exposure.
摘要:
RADIATION-SENSITIVE EMULSIONS AND ELEMENTS PARTICULARLY SUITABLE FOR USE IN HIGH INTENSITY OSCILLOGRAPHS ARE PREPARED BY ADDING TO A COLLOID-SILVER HALIDE EMULSION OF THE DEVELOPING-OUT TYPE OR DIRECT-WRITING TYPE, A LARGE AMOUNT OF A WATER SOLUBLE CHLORIDE SALT OF THE ORDER OF ABOUT 160 MOLE PERCENT BASED ON THE SILVER HALIDES AFTER DIGESTION AND PRIOR TO COATING THE EMULSION ON A SUPPORT.
