Basic dyes of formula (I): (in which n is 1 or 2; R1 is opt. substd. alkyl or aralkyl; R2 is H or as R'; R3 is H, Cl, Br, CH3 or OCH3; R4 is as R3, C2H5, OC2H5 or CN; R5 is H, Cl, CH3 or OCH3, or with R4 forms a condensed benzene ring; X is N or CH; Y is as R5, C2H5, OC2H5, benzyl, methoxycarbonyl or ethoxycarbonyl; A is an anion) are used for dyeing or printing of anionic-modified fibres, e.g. acrylonitrile polymers, polyesters and polyamides, in greenish-yellow to orange shades. Cpds. (I) give high strength, giving brilliant shades with very good fastness, esp. to light and hot-pressing.
