Abstract
A process for colouring a synthetic textile material or fiber blend thereof which comprises applying to the synthetic textile material a compound of Formula (1): A--N.dbd.N--D--N.dbd.N--E Formula (1) wherein: A, D and E each independently is an optionally substituted heterocyclic or carbocyclic group and at least one of A, D or E carries directly at least one --SO.sub.2 F group or carries a substituent to which at least one --SO.sub.2 F group is attached. A process for the mass coloration of plastics which comprises incorporating into a plastics material a compound or mixture thereof which is free from water solubilising groups, of Formula (1).
Claims7
A process for coloring a synthetic textile material or fibre blend thereof which comprises applying to the synthetic textile material a disazo compound of Formula (1):
- A--N.dbd.N--D--N.dbd.N--E (1)
- wherein
- A is phenyl or phenyl substituted by a group selected from NO.sub.2, SO.sub.2 F,--C.sub.1-6 alkyl and C.sub.1-6 -alkoxy;
- D is selected from 1,4-phenylene, 1,4-naphthylene, 4,4'-biphenylene and thien-2,5-ylene each of which is unsubstituted or substituted by a group selected from Cl, CN, C.sub.1-6 -alkyl, C.sub.1-6 -alkoxy and COOC.sub.1-6 -alkyl, and
- E is phenyl or quinolinyl each of which is unsubstituted or substituted by a group selected from SO.sub.2 F, C.sub.1-6 -alkyl, NHCOC.sub.1-6 -alkyl and NR.sup.1 R.sup.2 wherein R.sup.1 and R.sup.2 are each independently C.sub.1-10 -alkyl or C.sub.1-6 -alkyl substituted by a group selected from CN, OCOC.sub.1-6 -alkyl, COOC.sub.1-6 -alkenyl, phenyl and fluorosulphonylphenyl;
- provided that the disazo compound of Formula (1) contains at least one --SO.sub.2 F group.
A process for the mass coloration of a plastics material which comprises directly incorporating into the plastics material a disazo compound of Formula (1)
- A--N.dbd.N--D--N.dbd.N--E (1)
- wherein
- A is phenyl or phenyl substituted by a group selected from OH, NO.sub.2, SO.sub.2 F, C.sub.1-6 -alkyl and C.sub.1-6 -alkoxy;
- D is selected from 1,4-phenylene, 1,4-naphthylene, 4,4'-biphenylene and thien-2,5-ylene each of which is unsubstituted or substituted by a group selected from Cl, CN, C.sub.1-6 -alkyl, C.sub.1-6 -alkoxy and COOC.sub.1-6 -alkyl, and
- E is phenyl or quinolinyl each of which is unsubstituted or substituted by a group selected from OH, SO.sub.2 F, C.sub.1-6 -alkyl, NHCOC.sub.1-6 -alkyl and NR.sup.1 R.sup.2 wherein R.sup.1 and R.sup.2 are each independently C.sub.1-10 -alkyl or C.sub.1-6 -alkyl substituted by a group selected from CN, OCOC.sub.1-6 -alkyl, COOC.sub.1-6 -alkenyl, phenyl and fluorosulphonylphenyl;
- provided that the disazo compound of Formula (1) contains at least one --SO.sub.2 F group.
A disazo compound of Formula (1):
- A--N.dbd.N--D--N.dbd.N--E (1)
- wherein
- A is phenyl or phenyl substituted by a group selected from OH, NO.sub.2, SO.sub.2 F, C.sub.1-6 -alkyl and C.sub.1-6 -alkoxy;
- D is selected from 1,4-phenylene, 1,4-naphthylene, 4,4'-biphenylene and thien-2,5-ylene each of which is unsubstituted or substituted by a group selected from Cl, CN, C.sub.1-6 -alkyl, C.sub.1-6 -alkoxy and COOC.sub.1-6 -alkyl, and
- E is phenyl or quinolinyl each of which is unsubstituted or substituted by a group selected from OH, SO.sub.2 F, C.sub.1-6 -alkyl, NHCOC.sub.1-6 -alkyl and NR.sup.1 R.sup.2 wherein R.sup.1 and R.sup.2 are each independently C.sub.1-10 alkyl or C.sub.1-6 -alkyl substituted by a group selected from CN, --OCOC.sub.1-6 -alkyl, COOC.sub.1-6 -alkenyl, phenyl and fluorosulphonylphenyl;
- provided that the disazo compound of Formula (1) contains at least one --SO.sub.2 F group and at least one ester group.
