  • a high temperature development process has been known as an effective method of accelerating the development rate of silver halide photographic light sensitive materials.
  • the primary object of the present invention to provide an improved method for high temperature rapid processing which shows neither deterioration of the physical properties of an emulsion layer, nor any substantial increase in fog nor any reduction of developing speed by employing an aldehyde hardening agent together with effective anti-foggants for the aldehyde.
  • R and R are each hydrogen, an alkyl radical or form a hydrocarbon condensed ring therewith.
  • An additional advantage of the present invention is that it is not necessary to add to the light-sensitive material a compound capable of suppressing fog due to an aldehyde hardening agent because the compounds of the present invention are capable themselves of suppressing aldehyde fog effectively in a processing solution, and consequently the deterioration of the lightsensitive material during storage is prevented.
  • the compounds of the present invention are used in a developer together with an aldehyde hardening agent but in another method they may be used in a prehardening solution containing a hardening agent of the aldehyde type.
  • the preferred concentration of the compounds of the present invention in a developer or prehardener containing an aldehyde hardening agent varies within a range of from 20-800 mg, and most preferably, l300 mg per liter of solution, although the quantity of aldehyde present is also a factor.

  • the important feature of the compounds of the present invention resides in their use in a processing solution, but as an alternate method, they may have been incorporated previously in an emulsion (as opposed to a processing solution) so as to prevent fog resulting from the use of aldehyde.
  • a photographic material obtained by adding a compound of the present invention to an emulsion in a proportion of 40-400 mg per 1 g-mole of silver halide before coating is treated with a hardening developer or prehardener containing an aldehyde hardening agent, fog can be maintained at a low level.

  • EXAMPLE 2 The same X-ray film as that of Example 1 was exposed and developed as follows using three developers.
  • EXAMPLE 3 A commercial high speed negative film was subjected to sensitometric exposure by means of sensitometer and then developed at 20C for 7 minutes using the following four developers.
  • the prehardening and water washing steps prior to the first development may be omitted.
  • the time for the first development is shortened because of elevated temperature.
