Photographic material, e.g. color negative, reversal or positive film, color (reversal) paper or dye diffusion transfer or silver dye bleach material, contains benzofuranone compound with substituent promoting adsorption on silver halide

Spectrally-sensitized silver halide emulsion, useful in photographic material, e.g. color photographic camera or copying material, is supersensitized with 1-substituted 5-oxo-, 5-thio- or 5-imino-dihydro-1,2,4-triazole compound

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 photographic film has red-sensitive, cyan-coupling silver halide emulsion containing oxo-, thio- or imino-1,2,4-triazolidine, bisbenzothiazolyl trimethin cyanine and benzoxazolyl benzo-thi- or -selen-azolyl trimethin cyanine compounds

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
