Abstract

A silver halide material for colour photography, comprising a support, at least one blue-sensitive yellow-coupling silver halide emulsion layer, at least one green-sensitive, magenta-coupling silver halide emulsion layer, and at least one red-sensitive, cyan-coupling silver halide emulsion layer applied to the support and conventional intermediate and protective layers, the emulsion in at least one of the silver halide layers comprising not less than 80 mol-% AgCl and not more than 0.5 mol-% AgI, and the last-mentioned silver halide emulsion is doped with at least one compound of a metal in the groups (a) and (b), where (a) comprises rhodium, iridium, osmium, ruthenium, rhenium and cadmium and (b) comprises gold and platinum. The material has very good development kinetics.
