Definitions

• the present invention relates to a silver halide color-light-sensitive material, and more particularly to a reversal color light-sensitive material which has excellent properties for a sensitization treatment.
• the silver halide color light-sensitive materials typically resort to subtractive color reproduction using three primary colors.
• the color image is formed by the combination of three dyes derived from a yellow color-forming coupler, a magenta color-forming coupler, and a cyan color-forming coupler.
• magenta color-forming couplers nitrogen-containing heterocyclic compounds such as 5-pyrazolones are in general use. Such couplers have some disadvantages. Particularly, they are liable to restrain development. An emulsion layer containing such a coupler tends to be less sensitive and to yield a softer gradation than an emulsion layer of the same sensitivity and gradation containing a phenol-type coupler, naphthol-type coupler, and acetanilide-type coupler. Thus it is necessary to increase the sensitivity and gradation of the emulsion layer containing a magenta coupler and to control the amount of the emulsion to be applied in order to establish proper color balance. At a result, the magenta image tends to be inferior in graininess and sharpness to the other color images.
• magenta image of poor graininess is fatal to the light-sensitive material.
• the tendency toward low sensitivity is a disadvantage in sensitization treatment which is carried out in reversal color development as noted in Example 1 in order to raise the sensitivity by extending the usual development time of the first development or the black-and-white development.
• the tendency toward low sensitivity destroys the color balance of yellow color-forming, magenta color-forming and cyan color-forming in the sensitization treatment.
• reversal color light-sensitive materials containing such above-mentioned magenta couplers have poor properties for the sensitization treatment. This is a fatal drawback for reversal color light-sensitive materials, which must often undergo a sensitization treatment.

• gelatin hardener H-1 and surface active agent were added to each layer.
• polymer coupler latexes (a), (b), (c), (d), (e), and (f) were prepared from polymer couple (A) (for comparison) , and polymer couplers (I), (II) , (IV), (VI), and (XV) of this invention, respectively, in the following way.
• Each polymer coupler (20 g in the case of polymer coupler (A) for comparison, and an equimolar amount to the 20 g of polymer coupler (A) in the case of polymer coupler of this invention in terms of color forming unit moiety) was dissolved with heating in 60 ml of ethyl acetate, and the resulting solution was added to 300 ml of aqueous solution containing 15 g of gelatin and 1.2 g of sodiumlaurylsurte, followed by dispersion by a colloid mill. Finally, the ethyl acetate was removed under reduced pressure.
• samples (2), (3), (4), (5), (6), and (7) were prepared, respectively, in an analogous manner as for sample (1).
• Each latex was used in an equimolar amount of the magenta coupler of sample (1) in terms of coupler unit.
• the samples (1) to (7) were exposed to light and underwent the color negative process.
• the color development was performed for 3 minutes and 15 seconds for standard processing; and in the second experiment, the color development was performed for 6 minutes and 20 seconds for sensitization processing.
• composition of the processing solution used for each process is as follows:
• the coupler couplers, gelatin hardener, ultraviolet absorber, and sensitizing dyes used are as follows.
