Abstract (en)

[origin: EP0537545A1] A colour-photographic silver halide material with at least one silver halide emulsion layer, which contains at least one colour coupler and whose silver halide grains contain 40 to 90 mol % of AgCl and at least two zones of different halide composition, of which the outer zone has a chloride content at least 10 mol % higher than in the inner zone, and which is associated with a DIR compound whose reaction with the oxidised colour developer has a reaction rate constant k of > 2000 [l/mol . s], is distinguished by outstanding sharpness and colour reproduction even if it is processed by a rapid method.
