| titleOfInvention | Silver halide emulsion, production method thereof, and silver halide photographic light-sensitive material using the same |
| abstract | PROBLEM TO BE SOLVED: To provide a silver halide emulsion having a high aspect ratio and a small grain diameter and a small coefficient of variation between grains of an aspect ratio, and a silver halide photosensitive material having high sensitivity, hard gradation and excellent graininess. Through the following steps I) to IV), tabular silver halide grains having an aspect ratio of 8 or more with the [111] plane as the main plane are contained in an amount of 50% or more of the total projected area; A method for producing a silver halide emulsion characterized by satisfying the condition defined by the following formula (1) when the ripening temperature in the high temperature ripening step is T (° C.) and the ammonium ion concentration is C (mol / L). I) A low temperature nucleation step in which silver ions and halogen ions are added to the mother liquor by double jet to nucleate, II) a temperature raising step in which the temperature is raised from the low temperature nucleation step temperature to a high temperature aging step temperature, and III) High temperature aging step in which ammonium ions are added and ripened, IV) Particle growth step in which particle growth is performed Formula (1) 0.0550-0.0007 × T ≦ C ≦ 0.1162−0.0014 × T [Selection figure] None |
