Abstract

PURPOSE:To promote the adsorption of a prescribed cyanine dye and to increase the efficiency of spectral sensitization by adding the dye and a hypersensitizer before the formation of silver halide particles is completed. CONSTITUTION:An emulsion is produced by adding a cyanine dye (A) forming a J-associated body and a hypersensitizer (B) before the formation of silver halide particles is completed. A compd. represented by the formula may be used as the dye A and may also be used as the sensitizer B. In the formula, Z<21> is a group of atoms. forming thiazoline, thiazole, etc., each of R21-R23 is (substd.)alkyl, R24 is H, etc., each of V<21> and V<22> is F, Cl, etc., X21 is a counter ion residue and m21 is 0 or 1. More than two thirds of the dye A to be added and more than two thirds of the sensitizer B to be added may be added at the same time. All of the dye A and all of the sensitizer B may be simultaneously added.
