摘要:
Reactive pyridone azo dyestuffs of the general formula [I]: ##STR1## wherein D represents ##STR2## represents phenylene optionally substituted by lower alkyl, lower alkoxy, trifluoromethyl or halogen, ##STR3## represents phenylene optionally substituted by lower alkyl, lower alkoxy, halogen or acetylamino,--A--represents --CH.sub.2 --, --C.sub.2 H.sub.4 --, --OC.sub.2 H.sub.4 --, ##STR4## --SO.sub.2 NHC.sub.2 H.sub.4 --or --SO.sub.2 C.sub.2 H.sub.4 --, --X represents hydrogen, lower alkyl, lower alkoxy, nitro, trifluoromethyl or halogen,--Y represents alkyl, aryl or aralkyl optionally substituted by lower alkoxy or phenoxy,--Z--represents a connecting group of --O--or --S--,--V represents --CN or --CONH.sub.2,--W represents a 6-membered nitrogen-containing heterocyclic ring having at least one active halogen atom, andn represents 0 or 1.These reactive pyridone azo distuffs give dyeings which are yellowish to reddish orange in color which have excellent light fastness.
