Abstract
PURPOSE: To form a solarization type direct reversal silver halide photographic emulsion having stability and high sensitivity, and capable of obtaining high maximum density, by fogging silver bromide or iodo-bromide in the presence of a specified compound.
CONSTITUTION: A gelatin emulasion is prepared containing about 0.1W1 micrometer particle diameter silver bromide or iodobromide, preferably containing below 3 mole % of iodide, and then salts are removed. This emulsion is fogged in the presence of alkali (earth) metal chloride or ammonium chloride preferably in an amount of 0.006W0.018, or 2.0 × 10-6W2.0 × 10-3 mole per mole of silver halide, respectively, and a water-soluble gold compound in an amount of 3.0 × 10-6W 3.0 × 10-5 mole.
