Definitions

  • the invention relates to a method for producing a layer support for light-sensitive materials with an anti-roll layer on the back.
  • Gelatin layers are usually hardened using suitable hardening agents. the hardening agents crosslink the gelatin molecules with one another and thereby bring about a reduction in the water absorption or swellability of the layer, an increase in the melting point and an improvement in the mechanical strength of the gelatin layer.
  • Hardened gelatin layers are, above all, resistant to photographic treatment baths.
  • the light-sensitive gelatin-containing layers on the front of the carrier material are usually opposite gelatin-containing layers on the back of the carrier material.
  • the swelling behavior in the photographic treatment baths and the behavior of the layers during subsequent drying should be kept as identical as possible, so that the material maintains a good flatness during the entire working process and during later use.
  • the layers applied to the back are therefore called anti-roll, anti-curl or non-curling layers. Their layer thickness depends on the swelling behavior and the layer thickness of the front coating.
  • the anti-roll layers usually also contain various additives. These can be: wetting agents such as saponin, matting agents such as silica, plasticizers such as glycerin, organic acids such as citric acid, small amounts of other water-soluble high polymer compounds such as polyvinyl alcohol or antistatic agents such as sodium nitrate.
  • wetting agents such as saponin
  • matting agents such as silica
  • plasticizers such as glycerin
  • organic acids such as citric acid
  • small amounts of other water-soluble high polymer compounds such as polyvinyl alcohol or antistatic agents such as sodium nitrate.
  • the resistance of the anti-roll layers to the photographic treatment baths is achieved by hardening the gelatin with so-called hardening agents.
  • Known hardening agents for gelatin include chromium (III) salts, aldehydes, N-methylol compounds, dialdehyde polysaccharides, polyfunctional epoxides, aziridines, polyfunctional vinyl compounds, triacryl formal, substituted dichloro-s-triazines and others in Chap. 2 of the book "The Theory of the Photographic Process” by T.H. Substances described by James (London, 1977).
  • the hardening agents are either added to the gelatin-containing solutions before processing or they are applied as a separate solution to the gelatin layer already on a support. In the second case, the hardening agents diffuse into the gelatin layer, where they react with the petid chains.
  • Both methods can also be combined with one another in such a way that part of the hardening agent is added to the gelatin solution and another part is subsequently applied to the layer.
  • Each hardening agent known hitherto has one or the other disadvantage and does not have the wide range of possible uses, as is particularly desirable in the case of auxiliary gelatin layers which are applied to a support prior to emulsionation and are later in contact with the actual photographic layers.
  • DE-A-3 721 808 describes rapid curing by applying two successive coatings, the second upper coating being formed from a curing agent solution of chromium salts.
  • EP-A-303 789 has further described the synergistic effect of a premix hardener of 1,2,3-triazine and formaldehyde.
  • This premixing achieves faster and better gelatin hardening than the addition of the individual components without premixing.
  • the hardening reaction is accelerated by adding urea.
  • this recipe led to photographic fog in color emulsions.
  • this new hardening agent combination it was not possible to achieve an anti-roll coating with the required low water absorption capacity. This did not succeed even when additional aliphatic polyhydric alcohols were added to the anti-roll solution.
  • Another object of the invention is to provide a support for photosensitive materials, the anti-roll layer applied on the back has a water absorption capacity of less than 2.5 g H2O per 1 g protein, measured after 10 minutes of distilled water at 22 ° C. .
  • the ratio of the triazine-formaldehyde premix to the N-methylol compound is 1: 2.5 to 1:10.
  • the amount of total curing agent (triazine-formaldehyde premix and N-methylolo compound) is 3-6 g / 100 g protein.
  • the amount of aliphatic polyhydric alcohol is 30-50 g / 100 g protein.
  • the anti-roll layer solution can contain all other usual additives such as matting agents (e.g. silica), antistatic agents (e.g. inorganic salts), optical brighteners (e.g. stilbene derivatives), wetting agents (e.g. saponin) and the like.
  • matting agents e.g. silica
  • antistatic agents e.g. inorganic salts
  • optical brighteners e.g. stilbene derivatives
  • wetting agents e.g. saponin
  • the anti-roll layer solution can be applied with all customary application and metering methods, such as roller application, engraving or nipping methods, with subsequent air brush or roller doctor metering if necessary.
  • the anti-roll layer solution applied to the back of the support is dried directly from the sol mold, that is to say without prior gelation of the solution.
  • TAF 1,3,5-triacrylloyl-hexahydro-s-triazine
  • the anti-roll layer solution was applied to the back of the polyethylene-coated support by means of a roller application device and knife metering and dried out of the sol mold in a hot air duct at an air temperature of 130 ° C.

  • the web speed was 130 m / min.
