Abstract
The present invention relates to a silver halide color photographic light-sensitive material, in particular to a multilayer material which comprises a support provided with blue, green and red sensitive silver halide emulsion layers containing a yellow, a magenta and a cyan dye forming coupler, respectively. According to the present invention, a paper having characteristic curves of gamma as a function of the density is obtained by a color development of a light-sensitive material after digital exposure.
Claims11
A multilayer silver halide color photographic material which comprises a support having provided thereon at least one blue (B) sensitive silver halide emulsion layer containing a yellow dye-forming coupler, at least one green (G) sensitive silver halide emulsion layer containing a magenta dye-forming coupler, and at least one red (R) sensitive silver halide emulsion layer containing a cyan-dye forming coupler;
- wherein at least one of said at least one emulsion layers contains:
- silverchlorobromide, silverchloroiodobromide and/or silverchloroiodide emulsion grains, having a silver chloride content of 90 mol % or more,
- wherein at least one of said emulsion layers comprises a compound selected from the metal compounds represented by formula I
- [MXInLI(6-n)]m (I)
- wherein M represents Cr, Mo, Ni, Re, Fe, Ru, Os, Co, Rh, Pd, Ir, or Pt;
- XI represents a halogen ion;
- and LI represents an arbitrary ligand which is different from XI;
- n represents 3, 4, 5, or 6;
- and
- m represents 4−, 3−, 2−, 1−, 0, or 1+. in an amount of 10−9 to 10−6 mole per mol of silverhalide;
- wherein for said material after digital exposure with exposure times between 10−9-10−4 sec and after development with a dry to dry time between 30 and 240 seconds, the following sensitometric properties apply:
- 2.7<γ<3.5 for R, G and B at D=1±0.1;
- the γ change at densities from 1 to 0.8 is symmetrical with the density change from 1 to 1.2 within an accuracy of 0.3 γ units for R, G and B;
- and
- at 1.3<D<1.5 γR=γG=γB within 0.5 γ units;
- wherein D represents the density for R, G, and B layer and γ represents the gradation at a certain density.
Photographic material having RGB sensitometry curves essentially as depicted in FIG. 1 and FIG. 2.
