Abstract: A PROCESS FOR FAST DYEING A SHAPED ARTICLE OF A COPOLYMERIZATE OF (A) STYRENE-ACRYLONITRILE, METHACRYLIC ACID LOWER ALKYL ESTER OR ACRYLONITRILE AND (B) ABOUT 0.1 TO ABOUT 5.0 MOL PERCENT OF A VINYL COMPOUND OF THE FORMULA

R4-C(-R3)=C(-R2)-CO-N(-R1)-PH-A-X

WHEREIN R1 AND R2 EACH IS HYDROGEN OR AN ALKYL OF 1 TO 4 CARBON ATOMS, R3 AND R4 EACH IS HYDROGEN OR A GROUP -COOCH2,-COOC2H5,-COOC3H7 OR-COOC4H5, OR R1 AND R4 FORM A RING WITH A-CO-BRIDGE, PH IS PHENYLENE, ALKOXY-PHENYLENE OR CHLOROPHENYLENE, A IS A GROUP -SO2C2H4- AT THE M OR P POSITION TO THE AMIDO GROUP, AND X IS A GROUP OF -OSO2ME OR -OCOCH3 IN WHICH ME IS AMMONIUM, SODIUM OR POTASSIUM, WHICH COMPRISES TREATING SAID SHAPED ARTICLE WITH AN AQUEOUS SOLUTION OR DISPERSION OF A MONOAZO DYESTUFF HAVING REACTIVE HYDROGEN ATOM AT A TEMPERATURE OF ABOUT 90*C. TO ABOUT 120*C. AT A PH OF ABOUT 5 TO ABOUT 10.
