Dyes for dyeing hydrophobic fibers such as acrylics and polyesters of the formula:
AND QUATERNIZED DERIVATIVES THEREOF WHEREIN R''s are independently selected from hydrogen, halogen, hydroxy, alkyl, substituted alkyl, aryl, substituted aryl, cycloalkyl and the like; A is 0, N or S; n and p are integers from 0 to 15 N+P IS AT LEAST 2; Z IS AN INTEGER OF 0 OR 1; R IS AN INTEGER OF 0 OR 1; N+P+Z+R IS AT LEAST 3; M AND Q ARE THE NUMBER OF DOUBLE BONDS IN THE Cn and Cp moities; X AND Y ARE SELECTED FROM HYDROGEN, HALOGEN, LOWER ALKYL, LOWER ALKOXY, SULFONIC ACID AMIDE AND SUBSTITUTED DERIVATIVES THEREOF, CARBOXYLIC ACID AMIDES AND SUBSTITUTED DERIVATIVES THEREOF, LOWER ALKYLSULFONYL, CYANO, CARBALKOXY, NITRO, AND THE LIKE; AND D is a coupling component which is free from solubilizing sulfonic acid and carboxylic acid groups.

BASIC DYESTUFFS WHICH ARE FREE FRO ACIDIC GROUPS IMPARTING SOLUBILITY IN WATER AND WHICH CORRESPOND TO THE FORMULA
1,4-DI(V-),2-Q;5-(B-N=N-)BENZENE OR
1,2-DI(V-),4-Q,5-(B-N=N-)BENZENE
WHEREIN Q IS AN ELECTRONEGATIVE GROUP, R IS A COUPLING COMPONENT, ONE OF V IS HYDROGEN, ALKYL, CHLORINE OR BROMINE AND THE OTHER A -O- ALKYLENEAMINO MOIETY. THE COMPOUNDS ARE PREPARED BY COUPLING, CONDENSATION WITH AN AMINE OR HYDRAZINE OR BY ALKYLATION. THEY ARE USEFUL FOR DYEING SYNTHETIC FIBERS, YIELDING STRONG AND LEVEL DYEINGS OF GOOD GENERAL FASTNESS, ESPECIALLY FASTNESS TO WET TREATMENTS, LIGHT AND RUBBING.
摘要:
WATER-SOLUBLE BASIC DYESTUFFS WHICH CONTAIN A HETEROCYCLIC RESIDUE, THE QUATERNARY RING NITTOGEN ATOM OF WHICH IS BOUND TO AN ALKYL GROUP BELONGING TO THE DYESTUFF THROUGH AN OXYGEN BRIDGING COMPONENT. THE NEW DYESTUFFS YIELD ON POLYACRYLONITRILE FIBRE DYEINGS WITH GOOD GENERAL FASTENESS-PROPERTIES. THE NEW DYERSTUFFS PRODUCE INTENSE AND LEVEL DYEINGS POSSESSING A GOOD FASTNESS, ESPECIALLY A GOOD FASTNESS TO WASHING, PERSPIRATION, SUBLIMATION, CREASE-RESIST FINISHING, DECATIZING, HOE-PRESSING, RUBBING, CARBONIZING, WATER, SEA WATER, DRY CLEANING, CROSS-DYEING AND SOLVENTS, ON THESE FIBRES, WHICH MAY ALSO BE DYED IN ADMIXTURE WITH ONE ANOTHER. THE NEW DYESTUFFS OF THE INVENTION ALSO DISPLAY, INTER ALIA, GOOD STABILITY IN A WIDE PH RANGE, GOOD AFFINITY IN AQUEOUS SOLUTIONS OF DIFFERENT PH VALUES AND A GOOD FASTNESS TO KIER BOILING. FURTHERMORE, THE NEW DYESTUFFS RESERVE WELL ON WOOL AND OTHER NATURAL OR SYNTHETIC POLYAMIDE FIBRES.
摘要:
Basic dyestuffs that are free from acidic groups imparting solubility in water which contain at least one etherified hydroxylamino residue which is linked through the nitrogen atom to a carbon atom of the dyestuff molecule, the corresponding quaternated dyestuffs and double salts thereof which dyestuffs one useful for dyeing syntheric fibers in strong level shades with good light fastness and good general fastness properties with good reserve to natural polyamide fibers.
