Definitions

  • the present invention relates to a method for processing photographic silver halide light-sensitive elements and more particularly to a method for processing photographic silver halide light-sensitive elements using an aldehyde-containing gelatin hardening agent and an antifoggant.
  • R represents a lower alkyl group or a substituted alkyl group
  • Ar represents a phenyl group or a substituted I phenyl group
  • n is strength of the emulsion layers of the'light-sensitive elements in the high temperature developer or other processing solution must be prevented from being degraded. Therefore, it is necessary to increase the mechanical strength of the emulsion layer before development or during development and maintain the mechanical strength thereof throughout the development.
  • a photographic silver halide light-sensitive element is, before development, subjected to a prehardening processing in a prehardening solution containing an aldehyde type hardening agent.
  • the aldehyde compound remaining unreacted in the emulsion layer is removed by water washing or is made harmless by processing it in a solution before development.
  • Such a method has the advantages that the processing time is shortened by the high temperature development and the efficiency of the processing is improved but has the disadvantage that the nurnber of the processing steps is greater than those in the usual method.
  • the disadvantage is caused by the use of an aldehyde compound as the hardening agent, for example; when an aldehyde, particularly a dialdehyde, is added to a developer, the formation of fog of a black and white photographic film or a photographic color film processed in the developer is remarkably increased.
  • the formation of the fog caused by the addition of such an aldehyde can be prevented by using a strong antifoggant such as benztriazole or mercatobenztetrazole.
  • a strong antifoggant such as benztriazole or mercatobenztetrazole.
  • the use of such an antifoggant strongly supresses the progress of development at the same time, the sensitivity of the emulsion is greatly decreased.
  • FIGS. 1 and 2 show the amount of fog occuring in various films after being processed in various developer solutions.
  • an object of the present invention is to provide a process for processing a light-exposed photographic silver halide light-sensitive element without forming fog.
  • Another object of this invention is to provide a process fo preventing the formation of fog caused by processing'a photographic silver halide light-sensitive element in a processing solution containing an aldehyde-type hardening agent.
  • a further object of this invention is to provide a process for developing a photographic silver halide light-sensitive element without reducing the developing speed and the sensitivity of emulsion.
  • the present inventors have investigated the methods of achieving the above-mentioned objects and, as a result thereof, have found that the aforesaid objects can be achieved by utilizing the present invention. More specifically, the above objects of this invention can be achieved by incorporating, in a or 1, said n being 0 when the compound is an internal salt.
  • the lower alkyl group R the following may be used: a methyl group, an ethyl group, a propyl group and a butyl group and as the substituted alkyl group, a carboxymethyl group, a B-carboxyethyl group, a 'y-carboxypropyl group, a fl-hydroxyethyl group, a B-acetoxyethyl group, a B-sulfoethyl group, a 'y-sulfobutyl group, a 8- sulfobutyl group, a methoxyethyl group and the like.
  • substituted phenyl group Ar the following are examples: phenyl groups substituted by a lower alkyl group; a hydroxyl group, an alkoxyl group, a nitro group, a halogen atom, a carboxyl group, NHCOR (wherein R represents a lower alkyl group), or
  • R and R" each represents a lower alkyl group, an aralkyl group or an aryl group, R and R" being the same or different.
  • acid residual group X there may be illustrated the following: halogen ions, such as a chlorine ion or a bromine ion, a methyl sulfate ion, a p-toluene sulfonate ion, and the like.
  • the development processing steps in the specification of this invention mean a prehardening process and a development process.
  • the light-exposed photographic silver halide element be processed in a developer containing the compound represented by the above-mentioned general formula and an aldehyde-type hardening agent but thelightexposed photographic element may be processed in a prehardening solution containing an aldehyde-type hardening agent and the aforesaid compound or may be processed in a prehardening agent and thereafter in a developer containing the aforesaid compound.
  • the amount of the compound represented by the aforesaid general formula giving an effective antifogging effect in the case of incorporating the compound in a developer containing the aldehyde-type hardening agent is usually 20-400 mg. particularly -300 mg. per 1 liter of developer.
  • the proportion is higher than 400 mg., the development is excessively suppressed with the result that the sensitivity is reduced.
  • the amount is lower than 20 mg., the antifogging effect is very small.
  • an alkaline aqueous solution containing a developing agent such as N-methyl-p-aminophenol, dihydroxybenzene, 1- phenyl-3-pyrazolidine, phenylenediamine or derivatives thereof.
  • the aldehyde-test hardening agent used in this invention is a compound having at least one aldehyde group, such as formaldehyde, dimethylol urea, 'glyoxal, glutalaldehyde or the like, a sulfite thereof or a bisulfite thereof.
  • the process of this invention may be applied to the developing process for all photographic silver halide light-sensitive elements but may be particularly applied to a high temperature and high speed processing for black and white or color photographic elements.
  • FIGS. 1 and 2 of the accompanying drawings which shows that the sample processed in developer B or developer C showed less fog than the sample processed in developer A (control). Also, the gamma and the effective sensitivity in the former (B or C) were higher than in the latter EXAMPLE 2
  • Commercially available high speed black and white negative photographic light-sensitive films were exposed by using a standard sensitometer and each of them was developed for 8 minutes at 20 C.
  • EXAMPLE 3 The photographic films as in Example 2 were exposed by using a sensitometer. One sample was then processed for 2 minutes in prehardening solution A (an aqueous solution having a pH of 10.3 and containing 10 ml. of 25 percent glutalaldehyde per 1 liter of the solution) and another sample was processed for 2 minutes in prehardening solution B (an aqueous solution having a pH of 10.3 and containing 10 ml. of 25 percent glutalaldehyde and 100 ml. of Compound 10 per 1 liter of the solution). Thereafter, the samples were processed for 8 minutes at C. in developer D as in example 2. The results showed that the formation of fog in the sample processed in prehardening solution B was much less than that of the sample processed in prehardening solution A as in Examples l and 2.
  • the prehardening step and the water washing step before the first development in the so-called coupler-indeveloper type color developing system can be omitted, as well as reducing the period of time required for finishing the first development by conducting the development at a high temperature without being accompanied with the aforesaid drawbacks, which make the process of this invention very profitable.
