<p>Dyestuffs of formula (I) where X1 is the residue of a coupling component of the amino- or hydroxybenzene series, the heterocyclic series, the amino- or hydroxynaphthalene series or with a methylene group capable of coupling, Y is a direct bond or a divalent bridging group, p is 0-3 A is an anion and K1 is where R' and R" are (subst) alkyl or cycloalkyl or together form a heterocyclic group1 R3 and R4 are H, (substituted) alkyl, cycloalkyl or acyl, R8, R9 and R10 are (substituted) alkyl or cycloalkyl or can make a heterocyclic ring as can R' with R3 and/or R" with R4 are prepared by coupling an amine with a coupling component H-X1-Y-K1 circled positive. The dyestuff may be used for paper and polyacrylonitrile textile material.</p> |
