Definitions
- the invention relates to a color photographic silver halide material with improved Characteristics.
- So-called white couplers or redox-active are used to solve these tasks Connections used. These are usually pyrazolone couplers with a methyl group in the coupling site or around diffusion-resistant Hydroquinones, disulfonamidophenols and N-aryl-N'-acylhydrazine. These connections but can meet the requirements of practice as described above are not sufficiently fulfilled.
- Acyl residues R 1 can be residues of an aromatic or aliphatic carboxylic, carbamic, carbonic, sulfonic, sulfinic or phosphoric acid.
- the incorporation into a polymer chain can take place via an unsaturated group, for example a styrene, acrylic acid or methacrylic acid group.
- unsaturated group for example a styrene, acrylic acid or methacrylic acid group.
- a suitable monomer is, for example
- the compound of formula I can be made to a polymer via a polymer-analogous reaction.
- a polymer-analogous reaction For example, the following connection be bound to a polymer:
- R 2 is R 3 and n is m.
- R 1 is preferably hydrogen or acyl
- R 2 and R 3 are alkyl, the sum of the C atoms in the alkyl radicals R 2 and R 3 being 8 8.
- Preferred acyl residues are the residues of aromatic and aliphatic carboxylic acids.
- the position of the substituents relates to the oxygen.
- the position is 3 para-constant to the 2nd ring link.
- the other compounds mentioned are obtained in a corresponding manner. If the reactivity of the phenolic component is reduced, it can be aggravated Reaction conditions become necessary e.g. by increasing the temperature, Increasing the concentration of sulfuric acid in the melt etc. Furthermore, all or part of the sulfuric acid can be replaced by other acids e.g. by p-toluenesulfonic acid, methanesulfonic acid, phosphoric acid, polyphosphoric acid, Phthalic acid, trifluoroacetic acid, boric acid and the like. like.
- the compounds of formula (I) are preferably used in an amount of 5 to 1000 mg / m 2 , in particular 10 to 500 mg / m 2 .
- the compounds of formula (I) can also be present as a salt (phenolate); as Cations are particularly suitable for metal cations and ammonium ions Alkali metal ions and trialkyl or tetraalkylammonium ions.
- color photographic materials are color negative films, color reversal films, Color positive films, color photographic paper, color reversal photographic paper, color-sensitive materials for the color diffusion transfer process or the silver color bleaching process.
- the photographic materials consist of a support on which at least one photosensitive silver halide emulsion layer is applied.
- Suitable as a carrier especially thin films and foils.
- the color photographic materials usually contain at least one red-sensitive, green sensitive and blue sensitive silver halide emulsion layer and optionally intermediate layers and protective layers.
- these layers can vary be arranged. This is shown for the most important products:
- Color photographic films such as color negative films and color reversal films show in in the following order on the carrier 2 or 3 red-sensitive, cyan-coupling silver halide emulsion layers, 2 or 3 green-sensitive, purple-coupling silver halide emulsion layers and 2 or 3 blue-sensitive, yellow-coupling silver halide emulsion layers.
- the layers same spectral sensitivity differ in their photographic sensitivity, with the less sensitive sub-layers usually closer arranged to the carrier than the higher sensitive sub-layers.
- a yellow filter layer is applied, which prevents blue light from entering the to get layers below.
- Color photographic paper which is usually much less sensitive to light as a color photographic film, points in the order given below usually a blue-sensitive, yellow-coupling silver halide emulsion layer on the support, a green sensitive, purple coupling silver halide emulsion layer and a red sensitive, cyan-coupling silver halide emulsion layer on; the yellow filter layer can be omitted.
- Deviations in the number and arrangement of the photosensitive layers can occur to achieve certain results. For example, you can all highly sensitive layers in one layer package and all low-sensitive layers Layers to another layer package in a photographic film be summarized to increase sensitivity (DE-25 30 645).
- Essential components of the photographic emulsion layers are binders, Silver halide grains and color couplers.
- Photographic materials with camera sensitivity usually contain silver bromide iodide or silver bromide iodide chloride emulsions.
- Photographic copy materials contain either silver chloride bromide emulsions with up to 80 mol% AgBr or silver chloride bromide emulsions with over 95 mol% AgCl.
- the maximum absorption of that from the couplers and the color developer oxidation product Dyes formed are preferably in the following areas: Yellow coupler 430 to 460 nm, purple coupler 540 to 560 nm, cyan coupler 630 up to 700 nm.
- hydrophobic color couplers but also other hydrophobic components of the layers, are usually in high-boiling organic solvents dissolved or dispersed. These solutions or dispersions are then in one emulsified aqueous binder solution (usually gelatin solution) and lie after drying the layers as fine droplets (0.05 to 0.8 ⁇ m diameter) in the layers before.
- aqueous binder solution usually gelatin solution
- the usually between layers of different spectral sensitivity arranged non-light-sensitive intermediate layers can contain agents which an undesirable diffusion of developer oxidation products from a photosensitive to another photosensitive layer with different prevent spectral sensitization.
- Suitable connections can be found in Research Disclosure 37254, Part 7 (1995), p. 292 and in Research Disclosure 37038, Part III (1995), p. 84.
- the photographic material can also contain UV light-absorbing compounds, white toners, spacers, filter dyes, formalin scavengers, light stabilizers, antioxidants, D min dyes, additives to improve the stability of dyes, couplers and whites and to reduce the color fog, plasticizers (latices), Contain biocides and others.

- the layers of color photographic materials are usually hardened, i.e. the binder used, preferably gelatin, is by suitable cross-linked chemical processes.
- Suitable hardener substances can be found in Research Disclosure 37254, Part 9 (1995), p. 294 and in Research Disclosure 37038, Part XII (1995), page 86.
