<p>Acrylonitrile (co)polymer textiles are dyed in aqueous, neutral or acid medium at 60-100 deg.C. or at above 100 deg.C. under pressure by means of dyes (I) which are free from sulphonic acid groups. D is a (substituted) aromatic-carbocyclic or aromatic-heterocyclic group, R1 is H or CN, R2 is a (substituted) alkyl, aryl or heterocyclic residue, R is H, a (substituted) hydrocarbon residue or heterocyclic residue or a (substituted) amino group, where the residues contain substituents which are suitable for the addition of a proton, A is an anion, m= 1 or 2, Y is a direct bond or a divalent bridge, K+ is a group with the formula R1 has the formula I or II, R3 is a (substituted) (cyclo) alkyl residue or together with R4 and the vicinal N atom forms a heterocyclic residue, R4 is a (substituted) (cyclo) alkyl residue or together with R3 and the vicinal N atom forms a heterocyclic residue, R5 and R6 are H or (substituted) (cyclo) alkyl residues, R7, R8 and R10 are H or a (substituted) hydrocarbon residues, R9 is H or a (substituted) (cyclo)alkyl residue, R11 is H, a (substituted) amino group or a (substituted) hydrocarbon residue, R12 is a (substituted) hydrocarbon group, X is C or N, R3 with R5 and/or R4 with R6 and the vicinal N atoms, R7 and R8 or R7, R8 and R9 together with the N+ atom may form heterocyclic residues, and the group with formula I is the residue of a (partly) saturated ring with a few atoms, and the groups with formula II is the residue of an unsaturated ring, and these rings I and II may be further substituted.</p> |
