<p>Yellow-orange basic dyestuffs for fast dyeing/printing acrylonitrile (co)polymer and also acid modified polyesters and polyolefins, cellulosics, paper, have the formula (I): (where the R1 gps. are the same or different opt. substd. alkyl, or two or three of these gps. together with the quaternary N atom form an opt. satd. heterocycle; R7 is opt. substd. alkyl; R9 is halogen; R11 is -CO-Alkyl; R12 and R13 are halogen; R18 is 4 or alkyl; y is opt substd. alkylene; X- is an anion; n is 1 or 2). Cpds. are prepd. by reacting a cpd. of formula (V): (where E is the acid residue of an ester) with an amine N(R1)3.</p> |
