Abstract
1,240,968. Basic dyestuffs. CHEMIEKOMBINAT BITTERFELD VEB. 2 June, 1970, No. 26599/70. Heading C4P. Basic dyes according to the invention have the formula wherein R 1 is an alkyl radical containing up to 4 carbon atoms; R 4 is hydrogen, methyl, ethyl, propyl or benzyl; R 2 and R 3 are hydrogen, methyl or methoxy and may be the same or different; X is dimethylamino, diethylamino, trimethylammonium or triethylammonium and An is an anion. The dyes are obtained by diazotizing 5 - amino - 2 - methylbenzimidazole and coupling with an amine of the formula and alkylating the obtained dyestuff with e.g. a dialkylsulphate or an alkyl halide. Alternatively, an appropriate 1,3-dialkyl 5-amino-2- methylbenzimidazole is diazotized and coupled with an amine of the above formula.
