Uneven development is prevented by the positioning of a colloid layer for adsorbing the organic development inhibitor according to the present invention. Also, the interlayer color correction effect is increased due to the use of the organic accelerator and the interlayer color correction coupler. The colloid layer for adsorbing the organic development inhibitor prevents uneven development from occurring in this case. Uneven development will be explained in detail in Example 1 stated. below.

  • the colloid layer has also the function of adsorbing the development inhibitor residue once released in a developer, if any, namely the function of removing the development inhibitor residue from a development or appropriately controlling the diffusion of the development inhibitor residue in a developer when the development inhibitor residue is released in the developer. Therefore, it is preferable that the colloid layer of this invention be disposed on or under the photosensitive emulsion layer group, i.e., between the photosensitive layer group and the support.

Therefore, silver halide grains which have not been chemically matured or ripened or are silver iodobromide grains containing less than 10 mol percent silver iodide are preferred. Silver chloride grains are not preferred for this purpose.

  • the colloid layer is positioned between the photosensitive emulsion layer containing the interlayer color correction coupler or the organic accelerator for the interlayer interimage efffect and the photosensitive emulsion layer to which the interlayer interimage is provided.
  • the colloid layer captures the development inhibitor released from the photosensitive emulsion layer under the colloid layer to control the working realm of the development inhibitor in a planar direction and to prevent uneven development from occurring.
  • the colloid layer is disposed under the photosensitive emulsion layer, that is to say, at the support side of the photosensitive emulsion layer.
  • the colloid layer captures the development inihibitor released from thephotosensitive emulsion layer to control the development inhibitor from diffusing further and the action of the development inhibitor from spreading in a planar direction further, whereby the uneven development is prevented.
  • the colloid layer captures the development inhibitor released in a developer, whereby the developer is prevented from being contaminated by the development inhibitor.
  • the silver halide grains used in the colloid layer have a mean grain size of less than about 0.2 microns and are silver iodobromide or silver iodide which dissolves in the color developer with difficulty.
  • the colloid layer of this invention is preferably coated at a coverage of about 0.01 to 10 g, preferably 0.1 to 5 g silver per square meter.
  • the present invention not only is uneven development prevented but also the uniformity of the development processing can be remarkably improved as the result thereof because by the present invention the release of the organic development inhibitor in the developer, which is a decisive factor in developer contamination, can be prevented.
  • High-temperature development as used in this invention means development at a temperature higher than about 30C, preferably from about 30 to about 40 or 60C or higher. It is known as shown in Japanese Pat. No. 28836/1970 and French Pat. No. 2,132,675 that the iodine ion released at development is very easily captured by silver chloride or silver bromide in the silver halide grains in the adjacent silver halide emulsion layer due to a replacement reaction reducing the possibility of the release of the organic development inhibitor in the developer, and the replacement reaction is accelerated at higher temperatures to prevent the release of the organic development inhibitor in the developer.
