摘要:
A high sensitivity color photographic recording medium has at least two red sensitive component silver halide emulsion layer and at least three green sensitive component silver halide emulsion layers, the sensitivity of layers of the same spectral sensitivity increasing in the direction from the layer support upwards and the more sensitive red-sensitive silver halide emulsion being located between two of the green-sensitive silver halide emulsion layers.
摘要:
A color photographic recording material comprising at least one layer of which the primary sensitivity is blue, another layer of which the primary sensitivity is green and a further layer of which the primary sensitivity is red, gives satisfactory density graduations for details of high color saturation when a red sensitivity is produced in at least one layer, of which the primary sensitivity is green, and in at least one layer, of which the primary sensitivity is blue, the primary sensitivity being 8 to 25 DIN higher than the secondary sensitivity.
摘要:
Hydrophilic color-forming compounds such as couplers and color-providing compounds for the dye diffusion transfer process may be emulsified with the aid of oil formers when they are in admixture with aliphatic tertiary hydroxy amino compounds as specified hereinafter.
摘要:
A photographic recording material having at least 2 panchromatically sensitized silver-halide emulsion layers differing in speed, a DIR-compound and at least 2 yellow couplers of differing coupling velocity provides an improved graininess.
摘要:
For controlling in a color photographic material the gradation, graininess, sharpness, edge and interimage effect and thus improving the overall color reproduction thioether DIR compounds of the following formula are particularly useful: ##STR1## in which X is a group that if split off together with the sulfur atom forms a diffusing development inhibiting mercaptan, Y represents --O--, ##STR2## or --S--, Z represents the ring members completing a 6-membered heterocyclic ring, R.sup.1 is an aliphatic, araliphatic or aromatic hydrocarbon group, a heterocyclic group or acyl, and R.sup.2 is the same as R.sup.1 or hydrogen.
摘要:
A light-sensitive material containing in emulsified form photographic additives and a process for introducing these photographic additives in emulsified form into photographic hydrophilic colloid layers with at least one N-alkylphtalimide derivative of the formula ##STR1## in which R.sub.1 and R.sub.2 are as defined hereinafter; the material having improved stability properties.
摘要:
As quick-acting hardeners for protein-containing photographic layers, which do not adversely affect the sensitizers and color couplers in the photographic materials, carbodiimide compounds containing sulphobetaine groups are used.
摘要:
A light-sensitive color photographic material comprises four silver halide emulsion layer units, one for recording each of the yellow, magenta and cyan partial images and one which serves as a color correction layer. The latter mentioned silver halide emulsion layer is fogged, has a lower light-sensitivity than the light-sensitive partial image recording layer, and contains color couplers for producing a yellow to magenta masking image to compensate for the undesired side densities in at least two image recording layers.
摘要:
Equidensity images can be produced by imagewise exposure and photographic processing of a photographic material containing at least two silver salt emulsions which may be arranged in one layer as a mixture or in two layers, wherein one silver salt emulsion is a fogged direct positive emulsion and the other is a negative emulsion.
