Definitions
- Color photographic materials always contain UV absorbers for light stability to improve the image dyes present in the material after processing or to obtain. UV-rich daylight can bleach the image dyes.
- the compounds commonly used in photographic materials Absorption of UV light are, for example, aryl-substituted benzotriazole compounds (US 3,533,794, DE 42 29 233), 4-thiazolidone compounds (US 3 314 794, (US 3 352 681), benzophenone compounds (JP-A-2784/71), Cinnamic acid esters (US 3,705,805, US 3,707,375), butadiene compounds (US 4,045,229), benzoxazole compounds (US 3,700,455), aryl substituted Triazine compounds (DE 21 13 833, EP 520 938, EP 530 135, EP 531 258) and Benzoylthiophene compounds (GB 973 919, EP 521 823).
- UV-absorbing couplers or polymers which are obtained by pickling in one special layer can be fixed.
- a disadvantage of these organic compounds is that they are limited in themselves Dimensions are light stable. When the UV absorbing compounds by light destroyed, the image dyes begin to fade.
- the object of the invention was to provide UV-absorbing substances, which are suitable for long-term protection of photographic materials.
- TiO 2 pigments whose average primary particle diameter is 10 to 100 nm, preferably 15 to 30 nm, which are transparent and with conventional white pigments based on TiO 2 (rutile and anatase) an optimal particle size of about 0.2 ⁇ m have hardly any light-scattering properties. They are also colorless, especially if the proportion of other metal oxides is as small as possible and is, for example, less than 5% by weight, preferably less than 2% by weight, and are used in a specific layer.
- the TiO 2 pigments according to the invention are particularly advantageous if more than 80% of the primary particles have a diameter of less than 100 nm.
- Transparent TiO 2 pigments with the stated properties are known, for example, from Gunter Buxbaum, Industrial Inorganic Pigments, VCH Weinheim, New York, Basel, Cambridge, Tokyo (1993), pages 227 to 228.
- the TiO 2 pigments according to the invention are used in the color photographic material in a layer which is no further from the light source than the layer in which the dye to be protected from UV light and formed by the development is located.
- the TiO 2 pigments according to the invention are preferably used in a layer which is arranged closer to the light source than the layer containing the dye to be protected.
- the TiO 2 pigments according to the invention are used in particular in an amount of 0.3 mg to 5 g / m 2, preferably 30 mg to 3 g / m 2 of photographic material.
- the TiO 2 pigments according to the invention can be dispersed in a gelatin solution and thus cast into a layer. This results in a considerably thinner layer than with conventional UV absorbers, which are usually distributed in high-boiling organic solvents and must therefore be emulsified as fine droplets in a gelatin solution.
- the TiO 2 pigments according to the invention give the dyes of the photographic image obtained after color development permanent protection against UV light since, unlike organic UV absorbers, they are not destroyed by UV light.
- the TiO 2 pigments according to the invention are preferably added to color photographic print materials, which are color photographic paper and transparent color photographic film for display purposes.
- 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 the 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 bromoiodide emulsions, which may also contain small amounts of silver chloride can contain.
- 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 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 additionally 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). , Biocide and others included.
- Suitable compounds can be found in Research Disclosure 37254, Part 8 (1995), P. 292 and in Research Disclosure 37038, parts IV, V, VI, VII, X, XI and XIII (1995), p. 84 ff.
- 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.
- the material is exposed through a step wedge each with a filter which is permeable to red light, green light and blue light, so that a cyan, purple and yellow color separation is obtained.
- the exposed material is processed as follows: step time temperature Develop 45 sec 35 ° C Fix bleach 45 sec 35 ° C Water 90 sec 33 ° C
- the processing baths were prepared according to the following regulation:
- Examples 2a to 2f show the overall better light stability, especially with high amounts of radiation (24 million Lxh).
