Definitions

  • the invention relates to a photographic material, in particular a photographic recording material, with an NC layer, which is designed in such a way that damage to the material, in particular during drying, is avoided or at least reduced during the processing process.
  • Photographic recording materials e.g. 35mm or roll films consist of a transparent base, e.g. of cellulose triacetate and a plurality of layers applied on one side of the base, which consist essentially of gelatin, in which the photographically important components such as silver halide grains, color couplers and other substances are embedded.
  • NC layers non-curling layers
  • the compact laboratories are usually designed so that the beginning of a film to be processed is attached to a perforated drag belt and is transported with it through the device.
  • the end of the film is freely movable.
  • the film is usually dried with air at a temperature of about 50 ° C.
  • the object of the invention is to change the entry and strength of the E a curvature occurring during drying at least so that no more damage occurs to the emulsion layers.
  • E i -Krümmung the film before or after processing would adversely affect the flatness in the camera or in the printer.
  • the object can be achieved by adding a certain hydrophilic polymer to the NC layer and maintaining certain quantitative ratios with respect to the gelatin on the emulsion side to the gelatin in the N layer to the polymer according to the invention.
  • the amounts of polymer and gelatin should preferably be matched to one another such that the ratio of the water absorption capacity of the layers on the emulsion side to the water absorption capacity of the NC layer ( ⁇ WAM) is 1 to 1.5.
  • the polymer of the formula I particularly preferably makes up at least 90% by weight of the amount of the hydrophilic polymer.
  • it can also be a black and white silver halide recording material in which the total gelatin application on the light-sensitive side of the support is 8 to 12 g / m2 and in the NC layer 3 to 6 g / m2.
  • the polymers of the formula I have acid numbers of 30 to 340, preferably 50 to 200 mg KOH / g.
  • the compounds of the formula I are prepared by reacting polyester diols of the formula II with carboxylic anhydrides of the formula III or corresponding di- and tetracarboxylic acids at from 20 to 200 ° C. in a molar ratio of 1: 1 to 1: 2, if appropriate in inert solvents:
  • the condensation reaction is preferably carried out without solvent, in particular at temperatures from 50 to 150 ° C.
  • the alkyl groups have in particular one to four carbon atoms.
  • the polyester diols II are known, for example, from Ullmann's Encyclopedia of Industrial Chemistry, 4th edition, volume 19, p. 305 ff. They are produced by polycondensation of one or more diols with one or more dicarboxylic acids and / or one or more oxy acids. Diols and dicarboxylic acids are preferably used. The oxyacids can be used as lactones.
  • Ethylene glycol 1,2-propanediol, 1,3-butanediol, 1,4-butanediol, 1,6-hexanediol, neopentyl glycol, diethylene glycol are preferred.
  • Preferred dicarboxylic acids are succinic acid, adipic acid, phthalic acid, sebacic acid, dodecanedicarboxylic acid.
  • the lactone of an oxycarboxylic acid is e.g. Caprolactone into consideration.
  • the average molecular weight, determined from the OH number by the end group method, of the polyester diols of the formula (II) is about 500 to 20,000, preferably 800 to 5,000.
  • the molar ratio of polyhydric alcohol to polybasic carboxylic acid is greater than 1. Examples of polyester diols are listed in Table 1.
  • Carboxylic anhydrides of the formula (III) are, for example
  • hydrophilic polymers which can make up to 40% by weight, preferably up to 10% by weight, of the hydrophilic polymer according to the invention are both naturally occurring high-molecular compounds such as proteins, protein derivatives, cellulose derivatives, e.g. Cellulose esters, gelatin derivatives e.g. acetylated gelatin, phthaloyl gelatin, ureidogelatin, polysaccharides e.g. Dextran, gum arabic, casein, collagen derivatives, albumin as described in Research Disclosure December 1989 page 1003-1004.
  • proteins protein derivatives
  • cellulose derivatives e.g. Cellulose esters
  • gelatin derivatives e.g. acetylated gelatin, phthaloyl gelatin, ureidogelatin
  • polysaccharides e.g. Dextran, gum arabic, casein, collagen derivatives, albumin as described in Research Disclosure December 1989 page 1003-1004.
  • the NC layer can also contain plasticizer additives. Suitable plasticizers and monohydric and polyhydric alcohols, acid amides, esters, for example phosphate esters such as tricresyl phosphate, phthalate esters such as dibutyl phthalate, polyacrylic acid esters such as polybutyl acrylate, polyethyl acrylate, polyurethane latices with anionic, cationic or nonionic groups as listed in Research Disclosure 12/89 page 1006.
  • plasticizer additives Suitable plasticizers and monohydric and polyhydric alcohols, acid amides, esters, for example phosphate esters such as tricresyl phosphate, phthalate esters such as dibutyl phthalate, polyacrylic acid esters such as polybutyl acrylate, polyethyl acrylate, polyurethane latices with anionic, cationic or nonionic groups as listed in Research Disclosure 12/89 page 1006.
  • the NC layer can also contain aqueous microgels.
  • Aqueous microgels are water-swellable particles with an average particle diameter of less than 1 ⁇ m.
  • microgels are crosslinked polystyrene sulfonic acid salts, crosslinked poly (meth) acrylic acid salts, crosslinked poly (meth) acrylamides, crosslinked polymers with quaternary ammonium groups.
  • the NC layer according to the invention can be constructed in one or more layers, for example in two or three layers.
  • the "NC layer” always means the NC layer package.
  • a cellulose triacetate base of 95 ⁇ m thickness provided with an adhesive layer on both sides is coated on the front with a light-sensitive, 3-color structure, dry layer thickness 21.5 ⁇ m; Gelatin application 16.9 g / m2.
  • the dry layer thickness of the NC layer is 5.4 ⁇ m.
  • the layer is applied in one pass using a triple cascade.
  • the drying properties of this roll film are shown in Table 2.
  • 35 mm wide film strips are cut from the coated material (60 cm wide). These are exposed, developed, bleached, fixed, watered and dried.
  • the film was dried in a conventional drying cabinet with a hot air blower at 50 ° C.
  • the end of the film (total length 80 cm) is weighted with a clip of approx. 20 g weight.
  • the curvature of the film is measured at intervals of one minute in the beginning, every 20 seconds during the bulging phase, and then again every minute thereafter.
  • the values (curvature versus time) are plotted against each other and connected to form a curve. From the curve, the values A o , T o , E a K, D1, D4 and E15 defined in Fig. 1 are read.
  • Example 1 The values of Example 1 are shown in Table 2 below.
  • Example 2 The same light-sensitive three-color structure of Example 1 is applied to the front on a 95 ⁇ m thick triacetate base provided on both sides with an adhesive layer, and different NC layers are applied to the back, in which 2 different polymers or mixtures of polymers are added to the gelatin in the partial layer.
  • Polymer 1 is a reaction product of a polyester diol from adipic acid and neopentyl glycol with benzene-1,2,4,5-tetracarboxylic acid, acid number 73.
  • Polymer 2 is a polymer of the formula:
  • Polymer 3 is a polyester urethane made from a polyester diol, hexamethylene diisocyanate and diaminocaproic acid, the polyester diol being produced from adipic acid and neipentyl glycol (MW: 80,000).
  • An additional advantage of the NC layer according to the invention is the reduction of the flatness amphitude, ie the curvature of the film which is dependent on moisture is reduced.
  • Table 4 shows, the flatness difference in the particularly practical humidity range of 50-20% for the starting film according to Example 1 is significantly larger than that of the comparison films with NC layers, which contain polymer 1 according to the invention alone or in admixture with an additional polymer.
