Definitions

  • ABSTRACT A light-sensitive silver halide photographic material is developed in the presence of a development inhibitoryielding compound having the formula wherein X is halogen COOR or, -OZ, where Z is an alkyl group, aryl group, heterocyclic ring residue, acyl group, or SO -R (R is an alkyl group, aryl group or heterocyclic ring residue) and R is an alkyl group; and R is where each of R is an aliphatic group or aryl group or two of the R groups may, together with the adjacent nitrogen atom, for a heterocyclic ring residue, and Y is a group which, when the thioether linkage has been split, forms, together with the sulfur atom, a compound having a development-inhibiting action.
  • This invention relates to a development inhibitor yielding compound for silver halide photography. It has heretofore been well known to incorporate into a lightsensitive silver halide photographic material a compound capable of yielding a development inhibitor, depending on the density of image at the time of development of the photographic material (the said compound will be referred to as development inhibitoryielding compound, hereinafter).
  • the said compound is, in general, of such a type that it reacts with the oxidation product of a color developer to yield a development inhibitor.
  • Typical of such a compound is the so-called DIR coupler that is prepared by introducing into the coupling position of a coupler a group capable of forming a compound showing a development-inhibiting effect when it is released from the coupling position.
  • This coupler has such properties that when coupled with the oxidation product of a color developing agent, it forms a dye and, on the other hand, yields a development inhibitor.
  • a development inhibitor-yielding compound is used, in general, for such purposes as mentioned below.
  • the compound has the characteristic that it yields a development inhibitor in correspondence to the density of image at the time of development.
  • the thus yielded development inhibitor is present in the emulsion layer of the photographic material, the development of said layer is inhibited in relation to the image density, so that there may be expected the so-called intra-image effects such as control of image tone, fine graininess of image, and improvement in sharpness of image.
  • a novel development inhibitor-yielding compound is used, whereby the abovementioned disadvantages are overcome, and prominent wherein X is halogen COOR or, OZ, where Z is an alkyl group, aryl group, heterocyclic ring residue, acyl group, or SO R (R is an alkyl group, aryl group or heterocyclic ring residue) and R is an alkyl group; and R is or -SY, where each of R is an aliphatic group or aryl group, or two of R groups may, together with an adjacent nitrogen atom, form a heterocyclic ring residue, and Y is a group which, when the sulfur atom of the thioether linkage has been released, forms together with the sulfur atom, a compound having a development-inhibiting effect.
  • the development inhibitor-yielding compound used in the present invention forms a colorless compound even when reacted with the oxidation product of the color-devoloping agent. Since the thus formed colorless compound does not constitute any part of'the resulting image, the compound used in the present invention has the advantage that it can be applied singly, without using other compounds different in structure,
  • the compound used in the present invention has an extremely high reactivity with the oxidation product of a color-developing agent, and hence has the advantage that excellent intra-image and inter-image effects can be attained even when the compound is used in a small amount.
  • the compound has the advantage that it can be selected from various development inhibitor-yielding compounds of the aforesaid general formula which may be used as photographic material and, in extreme cases, it can be incorporated into only one layer to act on all layers.
