Abstract

1503112 Acidic monoazo dyes MONTEDISON SpA 12 Feb 1976 [13 Feb 1975 21 May 1975] 05591/76 Heading C4P [Also in Division Dl] Novel acid dyes have the Formula (I) in which R is methyl or ethyl, R<SP>1</SP> is H or methyl, and the carboxylic group is meta or para to the azo group. The dyes are prepared by diazotization and coupling. A process is claimed for colouring polyamide (nylon) fibres with the dye (I). The fibres may be streaked.
