Abstract
Abstract A CLASS OF CYCLAMMONIUM-5-AZO-PYRIMIDINE DYESTUFFS WHEREIN TWO OF THE CARBON ATOMS IN THE 2-, 4- AND 6-POSITION OF THE PYRIMIDINE RING ARE OCCUPIED BY AN OPTIONALLY SUBSTITUTED AMINO GROUP AND THE REMAINING ONE BY AN ETHERIFIED HYDROXYL OR MERCAPTO GROUP OR AN OPTIONALLY SUBSTITUTED AMINO GROUP AND WHEREIN THE CYCLAMMONIUM COMPONENT IS A MONO- OR POLYNUCLEAR AROMATIC HETEROCYCLIC SYSTEM WHICH CONTAINS A QUATERNIZED NITROGEN ATOM AS RING MEMBER; SUCH DYESTUFFS BEING DISTINGUISHED BY GOOD AFFINITY FOR ACRYLIC FIBERS, POLYESTER FIBERS AND POLYAMIDE FIBERS MODIFIED TO CONTAIN ACID DYESITES.
