摘要:
A thermally processable imaging element is disclosed having a protective coat overlying at least one thermographic or photothermographic imaging layer containing an organic silver salt and a thermally activated reducing agent for silver ion. The protective coat includes a film-forming binder comprised of a water dispersible polymer containing hydroxy pendant groups and, to reduce low density spots visible after thermal processing, a combination of anionic, non-ionic and fluorocarbon moiety containing surfactants satisfying formula defined selection criteria.
摘要:
Metallic salts of organic charge-transfer agents, such as TCNQ, TNAP, TCNE and DDQ and their derivatives, can be processed by an electron beam for a variety of useful electronic and optical applications. The metallic charge transfer salts can be used to deposit high resolution conductive lines directly without developing solutions or subsequent metallization steps. The compounds can also be employed in the conventional manner as resists for doping (i.e., ion diffusion or implantation) and to diffuse metals into substrates. In particular, elecronic devices, optical devices and image-storage devices are disclosed which can be formed by simple electron beam processed of metal charge-transfer salt films deposited on substrates.

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.

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.
