    摘要: A color photographic silver halide material, which has a support which comprises at least one blue-sensitive, yellow-coupling silver halide emulsion layer nearest the light source and at least one green-sensitive, magenta-coupling silver halide emulsion layer and at least one red-sensitive, cyan-coupling silver halide emulsion layer which are further from the light source than is the at least one blue-sensitive layer, and which contains at least one cyan masking coupler which has its maximum absorption above 650 mn, the red-sensitive layers have their maximum sensitivity at 620±20 nm and the absorption of the masking coupler at the maximum sensitivity of the red-sensitive layers is at most 70% of its absorption at 690 mn, is distinguished by improved color reproduction and color saturation in the magenta layer without loss of sensitivity.

    摘要: A color photographic silver halide material having a support, which material comprises at last one blue-sensitive, yellow-coupling silver halide emulsion layer and at least one green-sensitive, magenta-coupling silver halide emulsion layer and at least one red-sensitive, cyan-coupling silver halide emulsion layer, and which contains at least one masking coupler which has two chromophores which absorb in the wavelength range from 420 to 750 nm and are eliminable or decolorizable by coupling with the developer oxidation product, is distinguished by improved sensitivity associated with undiminished color purity.

    摘要: The production of tabular silver bromide-iodide emulsions and silver bromide-chloride-iodide emulsions with an aspect ratio 32, an iodide content from 1 to 40 mol % and a chloride content from 0 to 20 mol %, by the process steps of (a) silver halide nucleus precipitation, and (b) at least one further precipitation of silver halide, wherein rein at least one aromatic five- or six-membered, heterocyclic compound, which is free from—SH—,—SSO2H— and—SSO2R groups, is added in an amount from 10−9 to 10−4 mol/mol silver during nucleus precipitation or during the precipitation of an inner zone of the silver halide grain which is different from the nucleus precipitate, results in an improved speed/grain size ratio and in an increased stability of a photographic material which contains an emulsion produced in this manner.
