Abstract:
PROCESS FOR THE DYEING OR PRINTING OF TEXTILE MATERIALS MADE FROM POLYMERS OR COPOLYMERS OF ACRYLONITRILE, BY USING DYESTUFFS OF THE GENERAL FORMULA
(2,3-(-A-),4-(2-Z-PHENYL),7-(R1-N(-R2)-)-4H-CHROMENE)(+)
X(-)
WHEREIN R1 AND R2 EACH STANDS FOR A HYDROGEN ATOM OR OPTIONALLY SUBSTITUTED LOWER ALKYL GROUP, Z REPRESENTS A CARBOXYLIC ACID ESTER GROUP, A REPRESENTS A PHENYLENE RADICAL WHICH MAY CONTAIN NON-IONIC SUBSTITUENTS OPTIONALLY CONNECTED WITH ONE ANOTHER TO FORM A RING, BUT IS FREE FROM AMINO GROUPS, AND X$ REPRESENTS AN ANION AND WHEREIN THE BENZENE NUCLEI A MAY CONTAIN FURTHER NONIONIC SUBSTITUENTS.
