摘要： PURPOSE:To increase the contrast by forming a photographic silver halide emulsion layer contg. previously fogged silver halide particles and binder on one side of a support. CONSTITUTION:A silver halide such as silver bromide, chloride, chlorobromide, iodobromide or chloroiodobromide is precipitated in the form of particles, and after produced water-soluble salts are removed, the silver halide particles are fogged with a reducing agent combined optionally with a gold compound. The fogged silver halide particles are mixed with a hydrophilic binder such as gelatin, albumin, agar or polyvinyl alcohol to prepare a coating liq. This coating liq. is applied to a photographic support such as a metallic or resin film to form a photographic silver halide emulsion layer contg. hydrophilic binder. Plural such emulsion layers may be formed.

摘要： PURPOSE:To obtain a direct positive type photographic emulsion having very low sensitivity and suitable for a daylight photosensitive material for a photomechanical process for manufacturing a printing plate by simultaneously adding an aqueous silver salt soln. and an aqueous halide soln. to an aqueous soln. contg. hydrophilic colloid at a specified speed while keeping the silver potential at a specified value and by mixing them. CONSTITUTION:An aqueous silver salt soln. and an aqueous halide soln. are simultaneously added to an aqueous soln. contg. hydrophilic colloid in the pres ence of a water soluble rhodium salt at a speed below the critical speed of growth of existing silver halide particles while keeping the silver potential (EAg) at 100-200mV, and they are mixed to manufacture a photographic silver halide emulsion. This emulsion gives low Dmin and high contrast and can be used as an emulsion for a photosensitive material having very low sensitivity and handleable in a light room iluminated with a fluorescent lamp cutting ultraviolet rays, an incandescent lamp or the like. T emulsion is suitable for use in the manufacture of a printing plate having high dot quality.
