Definitions

  • novel photographic emulsion layers and elements of this invention comprise, before exposure to actinic light, silver halide crystals having associated therewith, in substantially greater than fog-inhibiting amounts, a silver mercaptide of a substituted thiourea having at least one SH group in one of its tautomeric forms, the latter compouind being characterized in that when admixed with an aqueous silver halide dispersion it protects the silver halide crystals to such an extent that when a silver halide dispersion protected by said compound is treated with 10%, by weight, aqueous sodium thiosulfate at least three times the amount of silver halide remains undissolved as in a similar dispersion successively treated with aqueous sodium hypochlorite and sodium thiosulfate, after vigorous agitation of the dispersions for 30 seconds at C.
  • the silver halide dispersion insolubility is determined by taking a 0.5-ml. portion of the silver halide dispersion (after each incremental addition of the candidate organic compound), adding about 0.1 to 0.2 ml. of 10% aqueous sodium thiosulfate solution and observing the turbidity after seconds.
  • Water-permeable organic colloid binding agents can be used and in some cases such binders can be used alone.
  • Such agents include water-permeable or watersoluble polyvinyl alcohol and its derivatives, e.g., partially hydrolyzed polyvinyl acetates, polyvinyl ethers and acetals containing a large number of intralinear groups, hydrolyzed interpolymers of vinyl acetate and unsaturated addition polymerizable compounds such as maleic anhydride, acrylic and methacrylic acid esters and styrene.
  • Suitable such colloids of the last-mentioned type were disclosed in US. Patents 2,276,322; 2,276,323 and 2,397,866.
  • a particularly preferred organic compound is 2- mercapto-4-phenylthiazole (hereinafter to be referred to as MPT).
  • MPT 2- mercapto-4-phenylthiazole
  • This compound is disclosed and claimed in my copending application Ser. No. 317,824, filed October 21, 1963, entitled Photographic Compositions, Layers and Elements which is a continuation-in-part of this application. Assuming that a single molecule of MPT could occupy an area of 28 square angstroms, it would require 1.5 10 molecules to occupy a molar surface area of silver halide. With a molecular weight of 193, this would require of MPT to insolubilize one mole of the silver halide.
  • Example II Example I was repeated except that other thiourea compounds, in the same amounts by weight, were examined in place of MPT. After photographic processing as described in Procedure A, the optical densities of completely unexposed areas and heavily exposed areas of the film were determined using a Western Electric RA-lOO-C Densitometer.
  • silver chlorooromide dispersion is treated with 10%, by weight, aqueous sodium thiosulfate (so that the resulting mixture contains 0.29 mg. of silver and 1 mg. of sodium thiosulfate), at least three times the amount of silver chlorobromide remains undissolved as compared with similar dispersion successively treated with a 5%, by weight, aqueous sodium hypochlorite and by weight, aqueous sodium thiosulfate (so that the resulting mixture contains 0.29 mg. of silver, 25 mg. of sodium hypochlorite and 100 mg. of sodium thiosulfate), after vigorous agitation of the dispersions for 30 seconds at 25 C.
