Abstract
PURPOSE: To obtain a silver halide photographic emulsion of high sensitivity, high contrast, and low fog, by adding specified silver halide grains, a merocyanine dye, and a specified 5-membered cyclic compound.
CONSTITUTION: (a) Silver halide grains (preferably, of grain diameter about 0.2W 1μ) consisting mainly of tetradecahedron grains composed of faces (100) and faces (111); (b) a merocyanine dye; and (c) a 5-membered cyclic compound represented by formula I or II (Y1 is O, S, Se, or N-R4; R1WR4 are H, alkyl, alkenyl, aryl, cyano, or the like, and R1 may link with R2 to form a ring; and n1, n2 are 1 or 2), or formula III (Y2 is O or S and at least one of R1 and R2 is mercapto) are mixed. Merocyanine dye b is added by 10-6W10-2 mole and 5-membered cyclic compound c by 10-5W10-2 mole per mol of silver halide a.
