| titleOfInvention | Disazo dyestuffs - for synthetic fibres, paints, plastics, and resins |
| abstract | Disazo dyestuffs of the formula (I) D1-N=N-A1-N(R')-R3-Z-R4-N(R2)-A2-N=N-D2 (D1 and D2 = residues of diazo components; R1 and R2 = H or alkyl; R3 and R4 = alkylene; A1 and A2 = p-phenylene; and Z = a colourless difunctional group pref. contg. at least one hetero atom, which when D1 and/or D2 contains a heterocyclic group and/or a quatermisable hetero atom, pref. is (1) free of ether or C-N-C linkages, and/or (2) is not a difunctional aliphatic hydrocarbyl group). (I) are used in finely divided form for dyeing all kinds of synthetic fibres. (I) contg. one or two quaterised diazo residues are esp. suitable for dyeing fibres of the polyacrylic type. Non-quaterised (I) are pref. applied by the thermofixing process. (I) are also useful for spin dyeing polyesters, polyamides and polyalkenes, and for pigmenting paints, plastics and resins. |
