IN WHICH R1 AND R2, INDEPENDENTLY OF ONE ANOTHER, STAND FOR A C1C17-ALKYL RADICAL, WITH THE PROVISO THAT THE SUM TOTAL OF CARBON ATOMS CONTINUED IN R1 AND R2 AMOUNTS TO AT LEAST 16 PREFERABLY TO 16 TO 25; Z1 STANDS FOR A HALOGEN ATOM, A NITRO, C1-C4-ALKYL, C1-C4ALKOXY OR AN ACRYLAMINO GROUP; M IS A NUMBER FROM 0 TO 3; Z2 IS A FUSED BENZENE RING; AND N IS 1 OR, PREFERABLE, 0, AND A PROCESS FOR THEIR PRODUCTION. THE DYESTUFFS ARE ESPECIALLY SUITABLE FOR THE DYEING OF SYNTHETIC FIBER MATERIAL FROM ORGANIC SOLVENTS.
IN WHICH X STANDS OF AN OPTICALLY SUBSTITUTED CYCLOHEXYL RADICAL; Y DENOTES A C1-C17-, PERFERABLY A C2-C6ALKYL RADICAL OR AN OPTIONALLY SUBSTITUTED CYCLOHEXYL RADICAL; Z1 STANDS FOR A HALOGEN ATOM, A NITRO, C1-C4-ALKYYL, C1C4-ALKOXY OR AN ACYLAMINO GROUP; M IS A NUMBER GROM 0 TO 3; Z2 IS A FUSED BENZENE RING; AND N IS 1 OR 0, AND A PROCESS FOR THEIR PRODUCTION. THE DYESTUFFS ARE ESPECIALLY SUITABLE FOR DYEING SYNTHETIC FIBRE MATERIALS.
摘要:
Basic azo-dyestuffs containing a quaternized pyridine- or quinoline carbonyloxy- or carbonylimino-radical bound to an aromatic nucleus directly or via an alkylene-, alkylene- oxy- or alkyleneimino bridge.
摘要:
The invention comprises basic dyes of formula wherein R1 is hydrogen or a C1-C8 alkyl group, R2 is a methyl or ethyl group, R3 is a chlorine or bromine atom, or cyano or C1-C8 alkyl-sulphonyl group, R4 is a hydrogen, chlorine or bromine atom and Z is a C1-C3 alkylene or -CHOH.CH2-group. The dyes are prepared by diazotizing an amine of formula and coupling the diazonium compound with a compound of formula The dyes are preferably used to colour articles made from polymers composed of more than 80% acrylonitrile in red, blue or brown shades.
