摘要:
A color photographic silver halide material which can be developed to form a negative, at least 95 mol % of the silver halides of which consist of AgCl, and which contains at least one light-sensitive silver halide emulsion layer, the silver halide of which contains at least one compound of formulae (I), (II) and (III):nullIrClnF6-nnull2nullM2nullnullnull(I)wherein n denotes 0 or an integer from 1 to 6 and M2null denotes 1 or 2 cations with a total number of 2 positive charges,nullFe(CN)6nullmnullMmnullnullnull(II)wherein m denotes 2 or 3 and Mmnull denotes 1 to 3 cations with a total number of m positive charges, 1 wherein o denotes 0, 1 or 2 and R denotes an alkyl, aryl or aralkyl, is distinguished under scanning exposure and on analogue exposure by sharp contrast which is independent of exposure time and by a stable latent image.
