Abstract
Abstract There is disclosed a silver halide color photographic material and a method for forming an image using the same. The silver halide color photographic material has a yellow-coupler-, a magenta-coupler-, and a cyan-coupler-containing silver halide emulsion layer, which respective layers are different in color sensitivity from each other, and non-photosensitive hydrophilic colloid layers, on a reflective support; and comprises (i) a reflective support prepared by covering at least the surface to be emulsion-coated of the support with a composition prepared by mixing and dispersing a white pigment into a water-resistant resin whose major component is a polyester obtained by polycondensation of a dicarboxylic acid and a diol, (ii) a silver halide emulsion of at least one emulsion layer comprising silver halide grains having a silver chloride content of 90 mol % or more, (iii) at least one non-photosensitive layer containing at least one color-mix inhibitor having a molecular weight of 350 or more, and (iv) a yellow coupler having a relative coupling rate of 0.20 or over.
