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

Spectrally sensitized photographic silver halide emulsions, useful in e.g. color negative, reversal or positive film, paper or dye diffusion transfer or silver dye bleach material, contain 4-hydroxy-3-oxo- or 3-imino-pyrazoline compound

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

Chemical sensitization of a silver halide emulsion, especially useful for color negative or reversal film, in presence of part of spectral sensitizer uses gold and selenium or tellurium sensitizers

Archive | 2000

Color photographic material, e.g. color negative film, has blue-sensitive tabular silver halide emulsion containing more antifogging agent than red- and green-sensitive emulsions

Borst Hans-Ulrich; Bell Peter; Kapitza Detlev; Buescher Ralf; Siegel Joerg

Color photographic material, e.g. color negative film, has blue-sensitive tabular silver halide emulsion containing more emulsion stabilizer than red- and green-sensitive emulsions

Borst Hans-Ulrich; Bell Peter; Kapitza Detlev; Buescher Ralf; Siegel Joerg

Archive | 2000

Color photographic material, especially color negative film, contains selenium and/or tellurium in green-sensitive emulsion and smaller amount in at least one emulsion of different sensitivity
