Definitions

  • Light sensitive photographic material like plates, films, diazo printing foils substantially consists of a support and-alight sensitive emulsion layer mostlycomposedzof proteins, especiallygelatin, albumins etc.
  • the isuperpolyamides chemically related to the proteins 1 combine in. themselves, so to speak, the properties'of thesupport hitherto used and ofthe'zwelleknown' binding. agents for-the light -'sensitive compounds.
  • Nonfiammable, mechanically excellent single-.layer.motion picture films are obtained inthis way as well as printing foils fast to tear-and shrinkage. Awide variation is possible in the selection ofthe light sensitive compounds. It is possible to apply.
  • silver halide salts usual in photography, furthermore chromium .and iron saltsfor chemographic and heliographic processes and also light sensitive organic v dyestuffs and their intermediatereaction products, for instance diazo compounds of p-diamines,
  • To charge the surfaces with light sensitive compounds may be accomplished by a printing process, as for instance in cloth printing.
  • titanium white or other pigments 55 may be added to the superpolyamide used in the production of the foils, so that in the following printing process images on a white or bright colored back-ground are formed.
  • Large sheetsand foils consisting of superpolyamides may thus be provided in a photographic manner with any pattern desired, for instance with a woodor marble design.
  • laminated sheets and foils and fabrics maybe built up of various superpolyamides in different stages of condensation in such a way, that the uppermost layer is made more capable of swelling, for instance in water, aqueous solutions and organic solvents than the middle layer- After introducing the light sensitive compounds the increased swelling properties may be wholly 15' or partly neutralized by an after-treatment, for
  • Example I A foil consisting of the polymerisate of epsilonaminocaprolactam is bathed 5 minutes in a 5 percent silver nitrate solution and after short washing again bathed 5 minutes in 5 percent potassium bromide. After drying this material can be printed and developed like ordinary photographic material and the silver image obtained plays the same role as silver has hitherto done in the ordinary photographic materials, chemically and physically, as final image and as intermediate image,for instance in the transitory stage of the color developing process, silver bleaching process, residual image and antidiazotate process. Such material may also be workedup according to the reversal process.
  • Example II A foil consisting of the polymerisate of epsilonaminocaprolactam. and containing a white pigment, for instance bariumsulfate or titanium dioxide is soaked 5 minutes in a solution of 5 percent potassium bromide and after short washing again 5 minutes in 5 percent silver nitrate solution. After drying the foils thus obtained may be printed like P. O. P. and may be fixed in the 4 usual way.
  • a white pigment for instance bariumsulfate or titanium dioxide
  • Example III Three foils consisting of the, interpolymerisate of epsilon-aminocaprolactam and p-aminobenzoic acid are dyed by imbibition each in one of the three primary colors for subtractive color reproduction and afterwards bichromatized according to Example III. By etching, as described in Example III, colored reliefs are produced and by superimposing these three reliefs in neutral colors are obtained.
  • Ea'ample V One or several dyestuffs suitable for the color bleaching process, for instance erythrosine,
  • Example VI A foil consisting of the condensation product of hexamethylenediamine and adipic acid is soaked in, a solution of 4 grams of the sodium salt of the sulfuric acid ester of leuco-4.4-dichloro-5.5'-dibromindigo, 4 grams cupferron (N-nitrosophenyl-hydroxylamine ammonium), cc. glycerol and 80 cc. water and afterwards dried. The vat dyestufi forms on the exposed places during exposure.
  • Fixing is done by soaking 5 minutes in warm water at 70 C.
  • Example VII A foil of the condensation product of hexamethylenediamine and adipic acid is soaked in a light sensitive solution consisting of 2.l.4.-diazonaphtholsulfo acid, resorcin and nickel sulfate.
  • the foils may be coated after drying prior to exposure or after development with a lacquer containing besides a cellulose ester and -ether a natural or synthetic resin and, if necessary, water-repellent substances like parafiin and softeners.
  • a light-sensitive photographic material in the form of a layer of afilm-forming linear superpolyamide which is insoluble in water, shrink-resistant and capable of being charged 5 with a substance sensitive to light from an light.
