Definitions
- the invention relates to a color photographic recording material by a special sensitization an increased sensitivity to light from the red spectral range having.
- the color-sensitive film usually becomes red-sensitive Layer package so sensitized that the maximum sensitization is about 650 nm and the flanks of the sensitization band towards shorter and longer ones Wavelengths, especially in the green spectral range, drop steeply.
- the Sensitization curve of a typical CN film is shown in FIG. 1. To this In this way, good color separation and high brilliance of the CN film are achieved.
- EP 357 082 describes hydrazine-substituted spectral sensitizers which are super-sensitizing can work.
- EP-A-0 409 019 e.g. a color photographic Recording material described with improved color rendering
- the result is achieved that, for example, both the green sensitive and the red sensitive silver halide emulsion layers by using one or several so-called gap sensitizing dyes an additional sensitization for light from the gap area between two neighboring ones Main spectral ranges, in the present case between green and red (580 - 620 nm) receive.
- the neighboring spectral sensitivity curves in the Range of the subspectral sensitivity increased so that when exposed in This area requires a maximum of 0.6 logarithmic exposure units are the same color density as in the area of the neighboring main spectral sensitivity to create.
- the sensitivity of the red-sensitive layer package can be increased without disadvantages for the color rendering in that the sensitization band in the area of the main spectral absorption red ( ⁇ > 620 nm) in all sub-layers of the red-sensitive layer package symmetrically, i.e. towards both larger ones as well as smaller wavelengths
- the setting of the sensitization band characterized according to the invention is achieved for example, by going out for the sensitization of the layers concerned of a mixture of sensitizing dyes, at least one of which is a Sensitization maximum in the range of the main spectral sensitivity has a or several other sensitizing dyes of the mixture have, compared to the sensitization maximum of the first-mentioned sensitizing dye shifted slightly to shorter and / or longer wavelengths and that the proportion of the latter sensitizing dyes in the mixture accordingly elevated.
- a conventional red sensitizing dye both a sensitizing dye with a short-wave shift Sensitization maximum (“short red”) as well as a sensitizing dye with long waves shifted sensitivity maximum (“long red”) and the The proportion of the latter dyes in the mixture can be increased accordingly by one adjust the sensitization band broadened according to the invention.
- the silver halide emulsions are sensitized in the usual way.
- the Sensitizing dyes can be used as a mixture simultaneously or individually in succession Silver halide emulsion can be added. The addition of one or more sensitizing dyes already during the grain growth phase and / or during the chemical ripening is possible.

- 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.
- Color photographic films such as color negative films and color reversal films indicate in the following specified order on the carrier 2 or 3 red-sensitive, teal-green domes 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 on differentiate the layers of the same spectral sensitivity themselves in their photographic sensitivity, being the less sensitive Sub-layers are usually arranged closer to the carrier than the more sensitive ones Partial layers.
- Deviations in the number and arrangement of the light-sensitive layers can lead to Achieving certain results can be done for example all highly sensitive Layers to form a layer package and all low-sensitivity layers another layer package can be summarized in a photographic film in order to Increase sensitivity (DE-A-25 30 645).
- Essential components of the photographic emulsion layers are binders, silver halide grains and color coupler.
- Photographic materials with camera sensitivity usually contain silver bromoiodide emulsions, which may also contain small amounts of silver chloride can.
- Photographic copying 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 the dyes formed from the couplers and the color developer oxidation product is preferably in the following ranges: yellow coupler 430 to 460 nm, magenta coupler 540 to 560 nm, cyan couplers 630 to 700 nm.
- the color couplers are the relevant ones Silver halide emulsion layer units or their sublayers spatially and spectrally assigned.
- Spatial assignment is to be understood to mean that the color coupler is in such a way spatial relationship to the silver halide layer in question is that a Interaction between them is possible, which is a pictorial match between the silver image formed during development and that from the color coupler color image generated. This is usually achieved by the color coupler in the silver halide emulsion layer itself or in an adjacent one possibly non-photosensitive binder layer.
- Spectral assignment means that the spectral sensitivity of the concerned photosensitive silver halide emulsion and the color of the spatially assigned color coupler generated partial color image in a certain relationship to each other stand, the spectral sensitivity of each individual color separation (red, Green, blue) assigned a complementary-colored partial color image (cyan, magenta, yellow) is.
- Color photographic films are used to improve sensitivity, graininess, Sharpness and color separation are often used when reacting with the compounds Developer oxidation product release compounds that are photographically active, e.g. DIR couplers that release a development inhibitor.
- the mostly hydrophobic color coupler, but also other hydrophobic components of the Layers are usually dissolved in high-boiling organic solvents or dispersed. These solutions or dispersions are then in an aqueous binder solution (usually gelatin solution) emulsified and lie after drying of the layers as fine droplets (0.05 to 0.8 mm diameter) in the layers.
- aqueous binder solution usually gelatin solution
- Suitable high-boiling organic solvents, methods for incorporation into the Layers of photographic material and other methods, chemical compounds to be incorporated into photographic layers can be found in Research Disclosure 37254, Part 6 (1995), p. 292.
- the usually arranged between layers of different spectral sensitivity non-photosensitive interlayers may contain agents that are undesirable Diffusion of developer oxidation products from a photosensitive in prevent another photosensitive layer with different 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, whiteners, 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.
