Azole disazo dyestuffs |
| abstract |
DISAZO DYESTUFFS IN WHICH TWO MONOAZO DYESTUFF MOLECUES OF THE GENERAL FORMULA D-N=N-A-N(-R1)(-R2) IN WHICH D REPRESENTS THE RESIDUE OF A MONOCYCLIC OR BICYCLIC DIAZO COMPONENT, A REPRESENTS A PARA-PHENYLENE RESIDUE AND R1 AND R2 EACH REPRESENTS AN ALKYL RESIDUE THAT MAY BE SUBTITUTED, ARE LINKED TOGETHER THROUGH THE RESIDUES OF THEIR COUPLING COMPONENTS BY A BIFUNCTIONAL BRIDGING COMPONENT Z WHICH HAS NO DYESTUFF CHARACTERISTICS, AND IN WHICH ONLY ONE OF THE NONOAZO DYESTUFF RESIDUES IS JOINED TO THE BIFUNCTIONAL RESIDUE Z DIRECTLY VIA THE AROMATIC NUCLEUS A. THE DYESTUFFS ARE USED TO DYE SYNTHETIC FIBERS SUCH AS POLYESTER FIBERS. THE DYEINGS SO OBTAINED ARE VERY FAST TO LIGHT AND TO SUBLIMATION. |
