Color photographic material, e.g. negative or positive film or paper or reversal film, contains development inhibitor releasing coupler with 1,2,3-triazolyl or tetrazolyl-5-thio inhibitor group

Production of a silver bromide-iodide emulsion with core-shell grains useful in color negative film uses 5-ring heterocycle with no mercapto or thiosulfonate substituents during double-jet precipitation of high bromide shell

Color photographic material, e.g. negative or reversal film or paper, with packets of silver halide emulsions of different speed for each color sensitivity has slow to medium layer with emulsions differing in grain size and iodide content

Silver halide color photographic material for both standard and high-speed processing contains an added mixture of fine and coarse silver halide emulsions with different iodide contents

Photographic color negative or reversal film has red-sensitive, cyan-coupling silver halide emulsion layer with maximum sensitivity in specified wavelength range and specified differences between this and speed at longer wavelengths

Color photography material of high sensitivity/fogging ratio both in fresh state and after storage contains at least two red sensitizers and a benzofuranone compound

Color photography material containing at least two red sensitizers, an o-hydroxybenzylamino derivative, a bis-benzothiazole compound, and a benzoxazole compound

Color photography material of high sensitivity and low fog after short development times contains at least two red sensitizers and a benzotriazole-substituted phenol with the benzene ring of the benzotriazole unit unsubstituted

Color photographic materials with better (green) sharpness have tabular crystal layers with defined crystal thickness relationships and green-sensitive layer further than red-sensitive layer from transparent support

Color photographic material with improved sensitivity-fogging balance and stability contains a thiocyanate in addition to seleniulm and tellurium compounds and is preferably chemically ripened with the thiocyanate present
