Abstract
2:1 - Monoazo dye chromium complexes which in the form of the free acids have the general formula <FORM:1091907/C4-C5/1> in which R is a lower (C1-4) alkyl radical and the benzene ring III is optionally substituted by one or more chlorine atoms and one of the benzene rings is substituted by a single sulphonic acid group are prepared by reacting one molecular proportion of chromium-containing azo compound which in the form of its free acid is of formula <FORM:1091907/C4-C5/2> wherein the symbols are as above with one molecular proportion of a 2,4-dichloro-6-lower alkoxy-1,3,5-triazine or with one molecular proportion of 2,4,6-trichloro-1,3,5-triazine and subsequently converting one of the two chlorine atoms attached to the triazine ring to a lower alkoxy group by reacting with an alcohol. The dyes give green-yellow shades when applied to wool, silk, polyamide and polyacrylonitrile fibres, leather and regenerated cellulose fibres.
