Abstract
1,229,356. Monoazo dyes. FARBENFABRIKEN BAYER A.G. 10 June, 1969 [29 June, 1968], No. 29268/69. Heading C4P. The invention comprises monoazo dyes of formula wherein the CF 3 group is in m- or p-position to -N=N- and R is H or a C 1-6 alkyl or cycloalkyl group which are prepared by coupling a diazotized trifluoromethylaniline with a 2- amino-8-naphthol-6-sulphonic acid. The dyes give red shades on wool and synthetic polyamide fibres.
