Definitions

  • the invention relates to a carrier material for thermally developable photographic layers. It relates in particular to the use of a coated paper as a support for such photographic layers.
  • Photographic materials that can be developed by exposure to heat are known and are described, for example, in "Imaging Systems” on page 122 f of K.I. Jacobsen and R.E. Jacobsen (The Focal Press, London, 1976) and in “Neblette's Handbook of Photography and Reprography", 7th edition, 1978, on pages 32, 33 and 570 (Van Nostrand Reinhold Company). They are also commercially available as so-called “dry silver” materials).
  • thermally developable photographic layers are at least one organic metal salt compound and at least one reducing agent. This principle applies both to thermally developable black and white image layers and to thermally developable color image layers.
  • silver halide, antifoggants, sensitizers, color formers, activators, catalysts and / or other additives for improving the image quality or image stability can be contained in one or more image layers or in adjacent layers.
  • the binder of a thermally developable photographic layer is either a water-insoluble plastic, e.g. Polyvinyl butyral, or a common water soluble binder e.g. Gelatin or polyvinyl alcohol, and the photographic layer is spread as a spreadable preparation using known coating methods and dried.
  • a water-insoluble plastic e.g. Polyvinyl butyral
  • a common water soluble binder e.g. Gelatin or polyvinyl alcohol
  • the organic metal compound is preferably an organic silver salt (for example Ag laurate, stearate, behenate, urazole, triazole, benzotriazole, tetrazole, carbazole, imidazole, or the like).
  • organic silver salt for example Ag laurate, stearate, behenate, urazole, triazole, benzotriazole, tetrazole, carbazole, imidazole, or the like.
  • organometallic compounds such as Hg - , Fe (III) - and above all Te compounds. Characteristic of thermally developable photographic materials is not so much the type of oxidizing metal compound but rather the fact that a visible photographic image is obtained in the exposed material after heat treatment and without the known use of aqueous process solutions. By heat treatment it is meant that the imagewise coated material is brought to a temperature between 80 and 250 ° C (preferably 100 to 200 ° C).
  • polyester film is the preferred backing material, but the papers coated with resin (e.g. polyethylene), which are commonly used for wet development, are also occasionally used.
  • resin e.g. polyethylene
  • Film carriers are particularly suitable when transparency of the carrier is desired. However, they have disadvantages if the carrier material is to be reflective. The reflectance of 85 to 90% that is common with white film material (see EP 119 830) is not always sufficient to achieve optimal image sharpness. In addition, footage is relatively inflexible and expensive.
  • the known resin-coated papers for example polyethylene-coated papers
  • the resin layer therefore deforms at development temperatures of 100 ° or more, and a separation between the photographic layer and the resin layer was even observed in individual cases when developed by means of hot rollers.
  • thermally developable photographic materials have also become known, in which a color image is formed which is transferred to an image-receiving material during or after thermal development by diffusion transfer.
  • the processes and materials are described, for example, in EP 76 492, EP 79 056, DOS 3 345 023, EP 119 470, EP 118 078, DOS 3 407 228, EP 121 765, EP 123166, EP 125 521, EP 131161 or DOS 3 422 455.
  • conventional resin-coated papers are less suitable as an image-receiving material because of the thermoplasticity of the resin layers.
  • a paper is used as a carrier material for thermally developable photographic layers or as an image receiving material for thermally developed color images, which contains a crosslinked binder or at least a crosslinked on a surface.
  • Bearing layer which is produced from radiation-curable material, the crosslinkable starting material consisting predominantly of unsaturated monomeric, oligomeric or polymeric substances and is crosslinked in or on the paper by means of ionizing radiation.
  • EP-A 159 493 discloses a photographic support material which contains a coating on at least one side, the binder component of which is predominantly made from unsaturated compounds and which is cured by means of low-energy rays. To prevent discoloration and fogging, this material additionally contains at least one unsaturated monomeric, oligomeric or polymeric hydroxyl functional substance, the molar concentration of the hydroxyl groups being equal to or greater than 2, specifically for layers to be developed wet as well as for layers to be developed dry.
  • Reducing substances of this type are often also a component of the thermally developable photographic layers and are jointly responsible for image formation.
  • the layers hardened with ionizing radiation directly as a substrate for thermally developed photographic layers or also as a receiving material for thermally developed color images, because the unsaturated compounds used for the production of the radiation-hardened layers in the commercial form always come with the addition of polymerization inhibitors are stabilized.
  • Papers coated with radiation-hardened binder can be translucent to transparent. In this form, they are preferably used for thermally developable black-and-white layers, such as those used for generating weather maps. On the other hand, they can be reflective due to the addition of white pigment and are mainly used in this form for supervisory images.
  • Papers coated or impregnated with non-pigmented radiation-curable mixtures for transparent images show a more uniform transparency after curing than papers coated or impregnated with solvent-containing preparations and then dried.
  • Papers coated with pigmented radiation-curable mixtures primarily benefit from the possible degree of pigmentation of the coating.
  • white pigment e.g. titanium dioxide
  • reflectance levels of up to 95% were measured on such layers, which enables the production of particularly sharp and brilliant top views.
  • impregnations and coatings made from radiation-curable mixtures are very temperature-resistant after curing by means of ionizing radiation.
  • the layers do not deform even when briefly used at a higher temperature of 200 ° C or more, and the coated or impregnated papers are more dimensionally stable than previously used papers with minor changes in their moisture content.
  • such papers can be applied using a contact hardening process, for example. according to DOS 30 22 709 have a surface quality comparable to that of foils combined with the flexibility of a coated paper.
  • all base papers suitable for photographic applications are suitable, which can be treated in a known manner with all radiation-curable mixtures known in principle and after hardening by means of ionizing radiation (for example electron beams or other high-energy radiation) directly or after use known adhesion-promoting intermediate steps such as the corona treatment or an adhesive layer with one or more photographic layers for thermal development and optionally a protective layer and / or optionally an antihalation layer or further auxiliary layers are coated.
  • the thermally developable photographic layers can belong to the group of black and white image layers or to the group of color image layers.
  • Against side receives a protective layer of Uchthof according to the composition in Example 4 of European Patent Application No. 119 830.
  • An approx. 130 g / m 2 heavy photographic base paper with a pre-sealing coating consisting essentially of polyvinyl alcohol and barium sulfate, which is coated on one side with about 25 g / m 2 of a mixture hardened under protective gas by means of electron beams with an energy dose of 35 J / g is coated after corona treatment with about 2 g / m 2 of a 1: 1 mixture of gelatin and trimethylvinylbenzylammonium chloride copolymer and used as an image-receiving material for a thermally developable photographic color image according to DOS 33 45 023.
  • the image-receiving material is brought into contact with the exposed layer of the photo material, and the image is developed by means of a heated drum and transferred to the image-receiving material by diffusion transfer of the dyes.
  • a paper with a reflective coating according to Example 2 is used as a carrier material for a thermally developable photographic layer and an antihalation layer in accordance with EP 119 830.
