Abstract

PURPOSE:To easily prepare for a short time on a commercial scale a single disperse system emulsion of high sensitivity, low fog, and high contrast by an ammonia method, by adding and mixing an ammoniacal silver nitrate aqueous solution and an acidic halide aqueous solution at the same time. CONSTITUTION:An ammoniacal silver nitrate aqueous solution and an acidic halide solution in an amount of 10-200%, preferably 40-150% based on the amount capable of perfectly neutralizing this ammoniacal solution are mixed by a simultaneously mixing method in an aqueous solution containing 0.05-0.06 mole per liter of NH<+>4 added perferably in the from of an ammoniacal water, 0.05-0.25 mole per liter of a halide, and a hydrophilic colloid substance, and having a pAg of 6-11 and a pH of 9-11. This permits a single disperse system emulsion having a mean particle size above 0.1mu, perferably above 1.0mu, and 95wt.% of the total particles is within + or - 20% of the mean particle size, preferably its + or -15%.
