Abstract
A color photographic element which comprises a light sensitive silver halide emulsion layer and a non-light sensitive interlayer containing a ballasted 5-carbamoyl-1,3-dihydroxybenzene compound. The element exhibits an improved ability to prevent oxidized developer from diffusing away from the imaging layer in which it formed and into other color records where it can form the wrong color dye.
Claims23
A multicolor photographic element containing a support bearing a cyan dye image-forming unit comprised of at least one red-sensitive silver halide emulsion layer having associated therewith at least one cyan dye-forming coupler, a magenta dye image-forming unit comprising at least one green-sensitive silver halide emulsion layer having associated therewith at least one magenta dye-forming coupler, and a yellow dye image-forming unit comprising at least one blue-sensitive silver halide emulsion layer having associated therewith at least one yellow dye-forming coupler which comprises a non-light sensitive interlayer containing a ballasted 5-carbamoyl-1,3-dihydroxybenzene resorcinol compound having neither an --OH or --NH-- group attached directly to the aromatic nucleus.
A multicolor photographic element containing a support bearing a cyan dye image-forming unit comprised of at least one red-sensitive silver halide emulsion layer having associated therewith at least one cyan dye-forming coupler, a magenta dye image-forming unit comprising at least one green-sensitive silver halide emulsion layer having associated therewith at least one magenta dye-forming coupler, and a yellow dye image-forming unit comprising at least one blue-sensitive silver halide emulsion layer having associated therewith at least one yellow dye-forming coupler which comprises a non-light sensitive interlayer containing a compound having a dihydroxybenzene nucleus represented by formula I:
- ##STR9## wherein:
- R.sub.1 is hydrogen or a coupling-off group except hydroxy or those that contain an --NH group attached directly to the dihydroxybenzene nucleus;
- each R.sub.2 is an independently selected substituent except hydroxy or those that contain an --NH group attached directly to the dihydroxybenzene nucleus;
- n is 0, 1 or 2;
- R.sub.3, and R.sub.4 are independently selected from hydrogen, an alkyl group and an aryl group;
- provided that any two of R.sub.2, R.sub.3 and R.sub.4 can be connected together to form one or more ring systems;
- and
- provided that the hydrophobicity of R.sub.2, R.sub.3 and R.sub.4 together is sufficient to ballast the dihydroxybenzene compound.
