Definitions
- the present invention relates to a deformable material for producing a deformed image without significant image degradation, said material has a good storage stability and is suitable for digital exposure with very short pixeltimes, large formats and automatic processing.
- Deformable materials with colour and/or black and white motives are used e.g. as protective and/or decorative foils particularly in the furniture industry, in which they are used as design elements to cover low- priced and/or light weight carrier materials and/or carrier materials that are critical to the conditions of their use; the configuration of deformable material and carrier material replacing much more expensive and/or heavier and/or less easier to handle and/or less resistant materials such as real wood, stainless steel or marble.
- the manufacture of deformed plastic pieces with any kind of representations like images, designs, patterns, letters and so forth usually proceeds by printing on an undeformed flat foil of a thermoplastic polymer and is then deformed using heat and pressure.
- the results obtained are unsatisfactory, because the printed pieces after deformation exhibit a loss in image quality, that is visible at all parts where the deformation has led to an elongation of the deformed material.
- a significant loss in image quality is observed after deformation at curved parts and still more so at sharp edges, which is particularly noticeable as a bright line and/or increase granularity following the curves and/or edges in homogeneously coloured dark areas, which is unacceptable, particularly in the case of decorated furniture.
- the printing processes require complicated prepress steps and are therefore expensive and are not suitable for the manufacture of individual designs with small production runs.
- Photographic layers which were laminated onto a support, have, for example, been disclosed in EP-A 0 250 657, US 3,871,119, EP-A 0 490 416 and EP-A 0 276 506 for the manufacture of materials for identity cards and in EP-A 1 189 108 have been disclosed for materials with a broader colour gamut.
- the layers can subsequently be covered with a protective foil, as disclosed, for example, in US 4,370,397 and GB 2,121,812.
- the disclosed ID-cards are all flat, so that there are no requirements regarding deformability and their suitability or otherwise therefor was not disclosed.
- laminatable photographic layers those with special binders have been disclosed, although neither of these options produces an optimum image quality.
- graininess realized with state of the art laminatable materials is unacceptably high.
- the DTR materials that are also known to be laminatable are not suitable for the furniture industry, because the two-sheet process has not been adapted to the large format automated processing needed in this field.
- colour photographic materials comprising on a 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.
- a support for reflective material paper coated on both sides with polyethylene and for transparent materials longitudinally and laterally stretched polyester is usually used. The deformation according to the present invention of such colour photographic materials is not possible.
- GB 2,321,977 and the corresponding W098/35269 disclose a mouldable photographic material comprising a thermoplastic base sheet, a primer layer providing a key for a light sensitive layer, and a protective thermoplastic foil, the foil being bonded to the light sensitive layer with an optical quality adhesive.
- a pixel is the smallest image area on the copying material, which can be addressed by the exposure apparatus .
- Conventional silver halide emulsions exhibit a too low sensitivity, due to an unsatisfactory reciprocity, which results in a too low contrast and insufficient maximum * density at such short exposure times .
- a similar reciprocity failure is also observed at exposure times above 10 s (long exposure times) , which are necessary for analogue exposure of large formats.
- the known deformable photographic materials are unsatisfactory with regard to the storage stability of the unexposed and unprocessed materials, in particular when the support of the photographic material contains additives like plastizisers, stabilizers, and so forth.
- a further advantage of the present invention compared to printing processes is the possibility to produce even single pieces as a proof or demonstration example.
- the deformable colour photographic recording material of the present invention is suitable for digital exposure even at pixel times lower then 200 ns, exhibits a very good storage stability of the unexposed and unprocessed material and gives high quality images
- said colour 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, wherein the silver halide emulsions have an overall silver chloride content of at least 95 mol% and at least one silver halide emulsion contains silver halide crystals that are doped with 10 to 700 nmol, preferably 10 to 500 nmol Ir.
- gelatin can be successfully used in the materials used in the process according to the present invention.
- the reason why the use of gelatin failed according to FR 968 638, but surprisingly was very successful for the present invention, may be the difference between single layer black and white materials like those described in FR 968 638, that essentially only contain silver halide crystals dispersed in the binder, and multilayer colour photographic materials according to the present invention, that also comprise softer materials like couplers in their layers .
- aspects of the present invention are realized with a deformable colour photographic silver halide material, the colour 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, wherein the silver halide emulsions have an overall silver chloride content of at least 95 mol% and at least one silver halide emulsion contains silver halide crystals that are doped with 10 to 700 nmol iridium.
- aspects of the present invention are also realized with a process for producing a deformed image comprising the steps of: exposing the above-mentioned colour photographic silver halide material, preferably digitally; conventionally processing the exposed colour photographic material to produce an image; and deforming the colour photographic material .
- a process for producing a deformed image comprising the steps of: exposing the above-mentioned colour photographic silver halide material, preferably digitally; conventionally processing the exposed colour photographic material to produce an image; and deforming the colour photographic material .
- deformation also known as moulding
- deformation refers to three-dimensional deformation in which an initially flat object e.g. a plate or a sheet is deformed to a three dimensional shape using a shaping tool to which pressure and/or heat is applied, in the course of which at least a part of the initially flat object is elongated (stretched) , the shape being maintained upon cooling and/or upon releasing the pressure.
- the out-of-plane deformation is usually of a greater measure than the thickness of the initially flat object, the thickness being defined as the distance between the surface to which the tool is applied and the opposite surface of the initially flat object.
- deformable as used in qualifying colour photographic silver halide material is the ability to undergo deformation as defined above.
- the term to deform means the process of deformation.
- deformable plastic as used in disclosing the present invention includes all polymers, which can be deformed, without fracturing, exhibiting cracks or thermally decomposing.
- deformable plastic includes all polymers, that are available in foil form and that are not stretched.
- conventional processing means chromogenic chemical colour processing as used for the processing of conventional photographic materials such as color papers, color films or display materials and is further specified in the following description.
- immediate and fast hardeners mean that the hardener is capable of hardening gelatin immediately after coating or at least several days after coating to such an extent that no further changes in sensitometry and swelling behaviour due to the presence of hardener occur.
- swelling is meant the difference between wet layer thickness and dry layer thickness upon aqueous processing of the material .
- silver nitrate (equivalent to AgX present) is used in the examples to characterize the silver halide emulsions means the weight of silver nitrate in a given amount of silver halide emulsion that results when the quantity of silver halide in the emulsion is hypothetically converted into the equivalent weight of silver nitrate.
- aspects of the present invention are also realized with a process for producing a deformed image comprising the steps of: exposing the above-mentioned colour photographic silver halide material, according to the present invention, preferably digitally; conventionally processing the exposed colour photographic material to produce an image; and deforming the colour photographic material .

- Exposure preferably is carried out digitally and proceeds preferably from the side remote from the support, but in the case of a transparent or slightly coloured support exposure can also be carried out through the support if a loss in sharpness is tolerable.
- the material comprises an antihalation layer, that is bleached during the chemical processing of the material.
- Suitable absorbing material for said antihalation layer is described in Research Disclosure 38 957, 1996, VIII., from page 610, herein incorporated by reference.

- the support is provided on the image side between the silver halide layers and the support with a layer reflecting white light and on the opposite side with a non-bleachable black antihalation layer as described in US 4 224 402, herein incorporated by reference.
- the conventional processing of the colour photographic material is carried out with development times between 15 and 130 s. Longer development times are necessary, if, for example, silver-rich materials are processed in order to attain a particularly high colour density.
- Deformable plastics are those which can be deformed, without fracturing, exhibiting cracks or thermally decomposing. All polymers, that are available in foil form and that are not stretched fall under the term deformable plastics .
- a good reference point for the temperature necessary for deformation is the glass transition temperature (Tg) .
- Deformation is usually done between the glass transition temperature and the melting point of the deformable plastic.
- the pressure needed for deformation can easily be tested; the higher the deformation temperature is with respect to the glass transition temperature, the lower the pressure needed. Just below the melting point only a very low pressure is needed.
- the time needed for the deformation can also be easily tested and adjusted. A higher temperature and/or a higher pressure results in a shorter time.
