  • DIR compounds As such a compound there has been known a so-called DIR compound as described in British Patent No- 953,454, and U.S. Patents 3,227,554, and 4,095,984 which undergoes coupling reaction with an oxidation product of an aromatic primary amine color developing agent to form a coupling product and release a development inhibitor. There has also been known a so-called DIR hydroquinone which undergoes alternating oxidation reaction with an oxidation product of a developing agent to release a development inhibitor. (These compounds will be hereinafter referred to as "DIR compounds”.)
  • Such a DIR compound releases a development inhibitor which serves to exhibit an edge effect which leads to an improvement in the sharpness, prevent the developed silver from increasing its size, thus improving the graininess, and exhibit an interlayer effect which leads to an improvement in the color reproducibility.
  • the DIR compound has an inherent disadvantage that when used in a large amount, it causes a deterioration in the sensitivity of the silver halide emulsion incorporated in the same layer. Therefore, in a color-sensitive layer consisting of a plurality of emulsion layers having different sensitiv ities, the deterioration in the sensitivity of the layer having the highest sensitivity is minimized and a DIR compound is incorporated more in layers having a lower sensitivity.
