Abstract

924,658. Photographic materials. MINNEAPOLIS - HONEYWELL REGULATOR CO. May 15, 1959 [May 26, 1958 (2)], No. 16791/59. Class 98 (2). A photographic silver halide print-out emulsion contains as sensitizer up to 20% by weight, based on the weight of silver halide, of the iodide of either lead or cadmium. The silver halide may be the bromide, which preferably contains some co-precipitated silver iodide. The emulsions may be further sensitized with thioura, thiocarbamide, thiosemicarbazide, pmethylamino-phenol sulphate or mercaptosuccinic acid, and they may include carriers such as pregelatinized dextrin, gelatin, starch, dextrin, silicones or polyvinyl alcohol, and suspending agents such as seaweed extracts. When the carrier is other than gelatin, the coated paper may be heat treated, e.g. up to 400‹ F. for from 10 to 30 seconds. Examples are given of the precipitation of silver halides by adding slowly an ammoniacal silver nitrate solution to hot aqueous potassium bromide, which in some cases contains potassium iodide, washing the precipitate formed, and dispersing it with cadmium iodide in starch solution, or with lead iodide and thiourea in dextrin solution. These dispersions are then coated on to paper, and heat-treated at 400‹ F. for 20 sees.
