    摘要: A photographic material is disclosed containing on at least one side of the support at least one light-sensitive silver halide emulsion layer characterised in that the light-sensitive layer and/or at least one non-light sensitive layer in water-permeable relationship with the light-sensitive layer comprises at least one compound having the general formula (I)R[O--CH.sub.2 --CH.sub.2 --S--(LINK.sup.1 --S).sub.x --CH.sub.2 --CH.sub.2 --O--(LINK.sup.2)].sub.y --OR (I)wherein each of LINK.sup.1 and LINK.sup.2 which may be the same or different represents a divalent linking group; R represents H, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or an acyl group; x is 0, 1 or 2, and y varies from 2 to 20.

    摘要: A colour photographic silver halide material with a support, at least one red-sensitive silver halide emulsion layer containing at least one cyan coupler, at least one green-sensitive silver halide emulsion layer containing at least one magenta coupler, at least one blue-sensitive silver halide emulsion layer containing at least one yellow coupler, at least one interlayer Z-1 beneath the lowermost red-sensitive silver halide emulsion layer and/or at least one interlayer Z-2 beneath the lowermost green-sensitive silver halide emulsion layer, in which Z-1 and/or Z-2 contains a silver halide emulsion which contains tabular grains with an aspect ratio of>2, an average diameter of a sphere of equal volume of.gtoreq.0.3 .mu.m and a diameter of a circle of equal projected surface area of the tabular grains of at least 0.3 .mu.m, is distinguished by improved red and/or green sensitivity.
