Abstract

1,186,277. Monoazo dyes. BADISCHE ANILIN- & SODA-FABRIK A.G. 20 July, 1967 [21 July, 1966], No. 33304/67. Heading C4P. The invention comprises monoazo dyes, free from sulphonic acid groups, of formula wherein R is a hydrocarbon or substituted hydrocarbon radical and Z is an indole radical linked in the 3-position. The dyes are made by coupling indoles with diazotized aminoterephthalic acid esters. The dyes give yellow shades on fibres of synthetic polyamides, polyesters, polyacrylonitrile, polyolefines and cellulose esters. In examples, dyes wherein R is methyl, ethyl, isobutyl, methoxyethyl, phenoxyethyl or ethoxyethyl and the indole radical is 2-phenyl- or -methyl-indole or N-#-cyanoethyl-2-methylindole are described.
