Textiles based on or of (co)polyacrylonitrile asym. dicyanoethylene or synthetic polyamides or polyesters modified with acid gps. are printed by impregnating with paste prepd. from polybasic organic acid and/or urea in addn. to stable liquid prepn. of SO3H-free basic dyestuff of formula:- (in which R is opt. substd. (cyclo)alkyl; R1 is opt. substd. alkoxy; A- is anion; aromatic rings B and/or D can be substd. further) and fixing. - Use of additives eliminates changes in shade which can occur when these dyestuffs are used in aq. soln.
