ABSTRACT:
Pyridone dyestuffs of the formula ##STR1## are provided wherein R.sub.1 is hydrogen or an optionally substituted alkyl, aralkyl, cycloalkyl, aryl or heterocyclic radical or an optionally substituted amino group, R.sub.2, R.sub.3, R.sub.4 each independently represent hydrogen, halogen, alkoxy, or optionally substituted alkyl or cycloalkyl, R.sub.5 and R.sub.6 each independently represent hydrogen or an optionally substituted alkyl, aralkyl, cycloalkyl, aryl or heterocyclic radical or R.sub.5 and R.sub.6, R.sub.3 and R.sub.5 and R.sub.4 and R.sub.6 form heterocyclic rings, Y is hydrogen or hydroxy, --CN, --COOR.sub.7, --CONR.sub.7 R.sub.8 or --COR.sub.7 or an optionally substituted alkyl, aralkyl, cycloalkyl, aryl or heterocyclic radical, and Z represents --CN, --COOR.sub.9, --CONR.sub.9 R.sub.10, --SO.sub.3 H, --SO.sub.3 .crclbar. or --COR.sub.9, where R.sub.7, R.sub.8, R.sub.9 and R.sub.10 each independently represent hydrogen or an optionally substituted alkyl, aralkyl, cycloalkyl, aryl or heterocyclic radical. The dyestuffs can be used e.g. as cyan image dyestuffs in photographic material, as diffusible dyes which may become mordanted in a receptor layer or as filter, antihalation or acutance dyes in photographic material.
