Abstract

Abstract Cationic triazinyl dyestuffs of the formula <IMAGE> +TR <IMAGE> wherein R11 and R12 independently of one another are H, Cl, Br, OCH3, OC2H5, CH3 or C2H5, X is a radical of the formula COCH3, CN, COOCH3, COOC2H5, CONH2 or COC6H5, Y and Z independently of one another are C2-C5-alkylene, R1 and R2 independently of one another are H, Cl, Br, OCH3, OC2H5, CH3 or C2H5, R3 and R4 independently of one another are hydrogen or C1-C4-alkyl, R5-R10 independently of one another are hydrogen, C1-C4-alkyl, beta - or gamma -hydroxy-C2-C4-alkyl, phenyl or benzyl, or R5 and R6, and/or R8 and R9 in each case together with the nitrogen, form a pyrrolidine, morpholine or piperidine ring, or R5, R6 and R7 and/or R8, R9 and R10, in each case together with the nitrogen, form a pyridinium or picolinium radical, and An(-) is an anion are especially useful for dyeing paper.
