    摘要: A color photographic film having a support, 2 or 3 red-sensitive, cyan-coupling silver halide emulsion layers, 2 or 3 green-sensitive, magenta-coupling silver halide emulsion layers, 2 or 3 blue-sensitive, yellow-coupling silver halide emulsion layers, conventional interlayers and protective layers together with a yellow filter layer arranged closer to the support than the blue-sensitive layers, wherein at least one green-sensitive silver halide emulsion layer is arranged further away from the support than all the other photosensitive layers, exhibits improved sharpness without color distortion if at least 50% of the projected surface area of the silver halide emulsion of the green-sensitive silver halide emulsion layer, of which there is at least one, consists of tabular silver halide grains having an aspect ratio of at least 3.

    摘要: The invention relates to a photographic recording material comprising a layer support and, arranged thereon, at least one photosensitive silver halide emulsion layer which contains an antifogging agent corresponding to formula (I) ##STR1## in which A, R.sub.1 and R.sub.2 are as defined in the specification. The antifogging agents according to the invention reduce fogging without significantly affecting gradation and improve the staility of the photographic material in storage.

    摘要: A color photographic material comprising at least one light-sensitive silver halide emulsion layer having preferably a non-diffusing color coupler associated to it and at least one non-lightsensitive binder layer containing a colloidal silver dispersion provides less contact fog and a better color reproduction if the non-lightsensitive binder layer containing the colloidal silver dispersion contains also a soluble iodide, particularly sodium, potassium or ammonium iodide. Alternatively the soluble iodide may also be contained in a non-lightsensitive binder layer adjacent that binder layer which contains the silver dispersion.
