Title:
PRODUCTION OF PHOTOGRAPHIC SILVER HALIDE EMULSION
Document Type and Number:
Japanese Patent JPH09218479
Kind Code:
A
Abstract:
To provide the method for producing the emulsion high in silver chloride content and superior in rapid processability and developing speed.
This silver halide emulsion contains at least 50mol% silver chloride and ≥30% of the surface area of each grain comprises (111) faces. The silver halide grains are formed in the presence of a compound represented by the formula in which R is a straight or branched alkylene group; Z is a polar substituent; M is an H atom or a cation for neutralizing the molecule; and X is an anion when Z is an ammonium salt.
