摘要:
A print material having 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 and at least one blue-sensitive silver halide emulsion layer containing at least one yellow coupler, characterised in that the silver halide crystals of the red-sensitive layer have a chloride content of at least 95 mol %, contain 20 to 500 nmol of iridium per mol of silver halide and the cyan coupler is of the formula 1 in which R1 means a hydrogen atom or an alkyl group, R2 means an alkyl, aryl or hetaryl group, R3 means an alkyl or aryl group, R4 means an alkyl, alkenyl, alkoxy, aryloxy, acyloxy, acylamino, sulfonyloxy, sulfamoylamino, sulfonarnido, ureido, hydroxycarbonyl, hydroxycarbonylamino, carbamoyl, alkylthio, arylthio, alkylamino or arylamino group or a hydrogen atom and Z means a hydrogen atom or a group eliminable under the conditions of chromogenic development, is distinguished in that it is equally ideally suitable for analogue and scanning exposure and exhibits very good latent image stability.
