摘要:
A color photographic silver halide material having at least one silver halide emulsion layer which is cyan coupling and contains a red sensitizer, at least one magenta coupling silver halide emulsion layer containing a green sensitizer and at least one yellow coupling silver halide emulsion layer containing a blue sensitizer on a support, in which the at least one blue sensitive halide emulsion layer contains a further spectral sensitizer (gap sensitizer) whose sensitization maximum lies between the sensitization maxima of the red and green sensitive silver halide emulsion layer and/or the at least one red sensitive silver halide emulsion layer contains an additional spectral sensitizer (gap sensitizer) whose sensitization maximum lies between the sensitization maxima of the green sensitive and the blue sensitive silver halide emulsion layer is distinguished by an increased range of gradations in the region of the maximum densities and a markedly improved detail reproduction in the region of high densities.

摘要:
A process for producing a deformed image comprising the steps of: digitally exposing a color photographic silver halide material, said color photographic silver halide material comprising on a deformable plastic support at least one blue-sensitive silver halide emulsion layer containing at least one yellow coupler, at least one green-sensitive silver halide emulsion layer containing at least one magenta coupler and at least one red-sensitive silver halide emulsion layer containing at least one cyan coupler; conventionally processing said exposed color photographic material to produce an image; and deforming said color photographic material.
摘要:
A color photographic recording material with a reflective support which contains a spectrally sensitized silver halide emulsion containing at least one sensitizer for the spectral region B in a layer free from color coupler adjacent at least one dye-producing silver halide emulsion layer sensitized for the spectral region A, the sensitivity of the spectrally sensitized silver halide emulsion of the layer free from color coupler being lower by 0.6 to 2.5 log H units than the sensitivity of the sensitized silver halide emulsion of the dye-producing silver halide emulsion layer, is distinguished by an extended gradation range in the region of the maximum densities and, hence, by distinctly improved fine detail resolution at high densities.
摘要:
Polymer composite material with biocide functionality, preferably for the use in agriculture, comprising at least one base polymer compound and at least one biocide active ingredient, wherein the biocide active ingredient is an organic biocide that can be emitted from the polymer composite material by diffusion and/or osmosis and method of its production.
摘要:
The storage stability of photographic color images obtained by chromogenic development may be improved by compounds of the formula I, which are capable of reacting with primary amines, in particular color developer compounds (reagent for primary amines). The compounds of the formula may be added to the color photographic recording material or to a treatment bath downstream from color development. Compounds of the formula I are moreover suitable as an additive to a spent photographic processing bath or its overflow in order to reduce therein the content of color developer compounds before the processing bath or the overflow is disposed of or regenerated for further use. ##STR1## In formula I: A means --OR.sup.2, --SR.sup.2 or --NR.sup.2 R.sup.3 ; R.sup.1 means H, alkyl, aryl, acyl, sulphonyl or a residue as in A or a residue which, together with A or together with Z.sup.1, completes a ring;R.sup.2 means H, alkyl, aryl, acyl, sulphonyl; R.sup.3 means a residue as in R.sup.2 or optionally a residue which, together with R.sup.2 and the N atom, forms a heterocyclic ring, Z.sup.1 and Z.sup.2 mutually independently mean: H, halogen, cyano, alkyl, aryl, acyl, a heterocyclic group, alkoxycarbonyl, aroxycarbonyl, sulphonyl, imino, imido, sulphamoyl, carbonamido or sulphonamido; wherein Z.sup.1 and Z.sup.2, together with the C atom to which they are attached, may form a carbocyclic or heterocyclic ring system.
