Definitions

  • FIG. 1 The accompanying drawings show in; greatly enlarged cross-sectional view the appearance of a representative photographic element contemplated by our invention.
  • layer represents a support such as paper, cellulose ester, etc.
  • layer lit the emulsion layer of the invention containing a mixture of silver halide and a 3-pyrazolidone compound.
  • the 3-pyrazolidone compounds employed inthe emulsions have thegeneral structure in which the various R groups repre sent substituents such as hydrogen, alkyl heterocyclicor aryl* groups, for-example, R can be benzothiazolyl or an -aryl;fgroup--of the benzene or naphthalene series, substituted or not;however, R cannot be a hydrogen atom inasmuch as 3-pyrazolidone compounds containing no substituent other than hydrogen in the l-position of the nucleus, such as 3.-pyraz- 1.
  • the '3-pyrazolidone compounds can be used in silver halide-emulsionsifor the purposes of the invention with gratifyingresults in a rather wide range of concentration.
  • Usefullresults can be obtained, for example, with from about 0.2 to 2.0 grams of the B-pyrazolidone compound per mol of silver nitrate used in making the emulsion and converted to silverhalide.
  • B-pyrazolidone compound per mol of silver nitrate used in making the emulsion and converted to silverhalide.
  • the particular silver halide infthe emulsioni is not especially critical nor is the particular'method used for preparing the emulsion.
  • oneior more of the.3.-pyrazolidone compounds cantbe added toemulsions containing mixtures of silver bromide, silver chloride and silver iodide such as present in emulsion' of well known types.
  • the 3-pyrazolidones are-particularly useful in conjunction with bromoiodide emulsions which normally develop slowly andinemulsions which normally require a short first development as in bleach redevelopment reversal processes.
  • the 3-pyrazolidone compounds are added in water solution to the emulsions at any stage in their preparation but are conveniently added after the final digestion'and just before coating. .As will be apparent, the emulsions may contain the usual addenda including .antifoggants, spreading agents, coupler compounds, etc.
  • Such emulsions zare adaptable to use in forming single as well as multi-layer films useful in color photography which customarily include two or more emulsion layers on -a support :sensitized to diiferent regions of the'visiblespectrum and which may or may not contain coupler compounds.
  • EXAMPLE 1 Samples of a finished washed bromo-iodide emulsion were provided. To the respective samples of melted emulsion were added aqueous solutions of the 3-pyrazolidone compounds indicated in the fololwing table. The samples were coated successively on a paper stock and dried. The samples were then given continuous wedge exposures and developed for 20 to 45 seconds both when the samples were fresh and after 3-day incubation at 120 F. and 60 percent relative humidity, development being carried out in a conventional Elon-hydroquinone developer. Sensitometric evaluation of the developed samples produced the data tabulated in the following table.
  • the bar gamma values in the table are a measure of the contrast of the developed samples and a description of the determination of this value is given in the American Standards Association Bulletin entitled Sensitometry and Grading of Photographic Papers, January 8, 1953.
  • the development acceleration effect of using the B-pyrazolidone compounds in the emulsions should be made between samples detioned previously, it appears essential that the 3-pyrazolidone compounds contain a substituent other than hydrogen in the l-position of the nucleus since compounds such as 3-pyrazolidone do not produce the desired effect 5 when incorporated into silver halide emulsion layers.
  • a light-sensitive photographic emulsion comprising a mixture of unexposed silver halide and a-3-pyrazolidone having the following general structure veloped for 20 seconds and the stabilizing eifect of the E2 compounds should be evaluated on the basis of the samples developed for 45 seconds. It will be apparent from 1 H the data that the 3-pyrazolidone compounds materially increase the contrast of the emulsion and stabilize the T emulsion against contrast loss on aging.
  • EXAMPLE 2 To a sample of a normally slow-developing brornoiodide emulsion used in reversal processes was added 8.77 milligrams of 1-phenyl-3-pyrazolidone per mol of silver nitrate used in making the emulsion and converted to silver halide. The emulsion was coated as usual on a paper base, exposed, developed in a caustic hydroqui none developer and evaluated sensitometrically.
