Definitions

  • One object of our invention is to-provide a simple and direct method of preparing photographic paper in which the paper support becomes semi-water resistant. Another object of our invention is to provide a photographic paper which tends to restrict penetration into the paper of processing chemicals and the like. A further object is to provide a process for improving the surface characteristices of photographic paper supports. An additional object is to provide a paper sizing material which can be used with a photographic emulsion free from emulsion frill. Another object is to provide a sizing material which reacts with cellulose fibers on the surface ice 2 of the paper and becomes an integral part of the paper. An additional object is to provide a gelatino-photographic emulsion with improved adhesion when coated on a paper support. Other objects of our invention will appear herein.
  • Ketene dimers have been known in the art for use in treating various compounds.
  • U. S. Patent 2,171,241, issued August 29, 1939, to Johnson discloses a process of modifying silk fibers by exposing the silk fibers to the action of a ketene dimer.
  • U. S. 2,383,863, issued August 28, 1945, to Hueter teaches a process for preparing ketene dimers.
  • Other disclosures show treatment for rendering textiles, fibers, and the like water repellent in which these materials are treated with higher molecular ethenones or ketenes and subjected to a mild heat treatment.
  • ketene dimers produced according to the Heuter process and used for producing water resistant paper when coated with a photographic emulsion, results in emulsion frill during the photographic developing process. Consequently, it would be expected that the use of ketene dimers would not be applicable for photographic purposes.
  • a sizing solution for photographic applications which is compatible with photographic emulsions and which is free from emulsion frill during photographicprocessing.
  • gelatin coating compositions which may contain other materials.
  • gelatino-silver halide photographic emulsions, dye containing compositions, and other gelatino coating compositions may have this material added thereto.
  • This addition aids in the bonding of these coatings to previous coatings containing stearoyl hexadecyl ethenone in the event that the emulsion is coated on a support containing stearoyl hexadecyl ethenone.
  • FIG. 1 shows a photographic paper having a baryta coating over the gelatino-ketene dimer size.
  • Figure 2 shows a photographic paper without the baryta coating, with the photographic emulsion coated directly on the gelatino-ketene dimer sized paper.
  • Figure 3 shows a photographic paper coated with a gelatino-silver halide photographic emulsion containing a ketene dimer.
  • the starting compound used to prepare the ketene dimer may be one of those disclosed by Heuter. However, we prefer to use the ketene dimers in which the starting material is stearic or lauric acid.
  • the paper is sized by immersing it in a solution of gelatin and ketene dimer although the sizing solution may be applied by conventional means such as dip roller, spray coater and the like. Following this operation, the paper is dried and sensitized by coating with a photographic emulsion containing light-sensitive silver halide salts. In some grades of paper the paper is baryta coated and dried at a temperature of from ISO-250 F. followed by coating with a photographic emulsion containing light-sensitive silver halide salts.
  • the ketene dimer may be dispersed in water as shown above for preparing a paper size. It may also be dispersed by heating in methanol, ethanol or the like to a temperature of from 115 to 140 F., preferably to about 120 F. and then added directly to the gelatino-photographic emulsion which is usually at a temperature of above about 90 F.
  • the paper coating composition containing stearoyl hexadecyl ethenone is maintained at a temperature of from 85-125 F. during the coating operation to obtain optimum results in coating and stability of the disper- $1011.
  • Example 1 A gelatino-silver halide photographic emulsion was prepared for sensitizing photographic paper base. Stearoyl hexadecyl ethenone equal to 22.5% of the weight of the gelatin in the emulsion was dispersed by heating 140 F. in 40% of its weight of methanol. This dispersion was added hot, directly to the photographic emulsion which was then coated in the normal manner on supports sized with compositions containing stearoyl hexadecyl ethenone. Other amounts of stearoyl hexadecyl ethenone, including 34.75, 22.5, 12.25 and 6.1% based on the weight of gelatin, were also used. Good bonding was obtained between the support and the emulsion in all of the above applications.
  • Example 2 A 100% beaten rag fiber sheet was made containing rosin size, aluminum chloride, load (TiO melamine formaldehyde and heater gelatin. The paper was surface sized with a two bath operation containing stearoyl hexadecyl ethenone and 0.5% gelatin in the first pan and 1% gelatin in the second pan. Normal drying and calendering conditions were observed throughout the making.
  • Example 3 A 100% beaten rag fiber sheet was made containing aluminum chloride, load (TiO melamine formaldehyde, and beater gelatin. The paper was surface sized with stearoyl hexadecyl ethenone and gelatin as shown in Example 2.
  • Example4 The same type of 100% beaten rag fiber sheet, chemicals and surface sizing as described under Example 3 were used in preparing photographic paper base which was coated with a baryta-gelatin coating.
  • Example 5 A 100% beaten rag fiber sheet was made containing rosin size, aluminum chloride, load (TiO melamine formaldehyde, and beater gelatin. The paper was surface sized with a one bath operation containing stearoyl hexadecyl ethenone and 2 to 4% gelatin.
  • Example 6 A 100% wood base sheet was made containing A-size, aluminium chloride, melamine formaldehyde, starch, and beater gelatin. The paper was surface sized with a one bath operation containing stearoyl hexadecyl ethenone and 2 to 4% gelatin.
  • Example 7 A beaten wood base sheet was made containing A-size, aluminum chloride, load (TiO melamine formaldehyde, starch, and beater gelatin. The paper was surface sized with a one bath operation containing stearoyl hexadecyl ethenone and 2 to 4% gelatin.
  • Example 8 A 100% beaten wood base sheet was made containing aluminium chloride, load (TiO melamine formaldehyde, starch, and heater gelatin, but no A-size. The paper was surface sized with a one bath operation containing stearoyl hexadecyl ethenone and 2 to 4% gelatin.
  • Example 9 A 100% wood base sheet was made containing aluminum chloride and melamine formaldehyde.
  • the paper was sized by various methods with a solution of stearoyl hexadecyl ethenone and /z% gelatin.
  • the hopper, suction slide hopper, nip, and spray methods were all comparable to the size press method previously described.
  • Example 10 A 100% wood base sheet was made containing A-size, hydrochloric .acid, melamine formaldehyde, beater gelatin, and starch. The paper was sized with a solution of stearoyl hexadecyl ethenone and /2 gelatin.
  • the finished print on paper sized with the gelatin-stearoyl hexadecyl ethenone sizing had much less tendency to stain than a print on regular stock which did not contain the stearoyl hexadecyl ethenone-gelatin sizing.
  • the stearoyl hexadecyl ethenone-gelatin sizing may be applied to rag or wood fiber by surface sizing, nip sizing or spray sizing. It may also be applied to one side of the sheet to improve the coatability of subsequent applications such as baryta and the like.
  • this sizing material provides a highly improved surface on which for some purposes may be deposited a photographic emulsion directly without requiring a baryta coating placed over the sized paper. Consequently, the use of our sizing material will serve to improve photographic papers as will as save time and money for the photographic processors who will not now need to spend as much time in washing the photographic prints.
  • This ketene dimer is compatible with photographic emulsions and. free from photographic activity. It not only can be used to size photographic paper base, but also can be used as a component in photographic emul- 5 sions. When used in a photographic emulsion it enhances adhesion to the paper base and also improves the fiowability of the emulsion onto the paper support and results in more uniform photographic paper.
