摘要：
AZO DYESTUFFS OF THE FORMULA
(A-N=N-D-)-PYRIDINE; 1-R1,(A-N=N-D-)-PYRIDINIUM X(-)
IN WHICH A REPRESENTS THE RESIDUE OF A COUPLING COMPONENT FREE FROM SULPHONIC ACID AND CARBOXYLIC ACID GROUPS, D REPRESENTS THE RESIDUE OF A FIVE-MEMBERED HETEROCYCLIC RING WHICH CONTAINS THE PYRIDINE RESIDUE BOUND DIRECTLY TO A CARBON ATOM OF THE RING, R REPRESENTS AN ALKYL, ARALKYL OR CYCLOALKYL RESIDUE, X REPRESENTS AN ANION AND N STANDS FOR 1 OR 2. THE DYESTUFFS ARE SUITABLE FOR DYEING AND PRINTING SYNTHETIC FIBRES, WHICH PRODUCE INTENSE AND LEVEL DYEINGS AND PRINTINGS POSSESSING GOOD FASTNESS PROPERTIES SUCH AS GOOD FASTNESS TO LIGHT, WASHING, PERSPIRATION AND SUBLIMATION, AND WHICH DISPLAY GOOD STABILITY IN A WIDE PH RANGE.
