More Information
Summary:The invention comprises dyestuffs of the formula <FORM:0895399/IV (c)/1> where R is a benzene radical which may be further substituted, X and Y are each nitrogen bridges, Z is hydrogen or a sulphonic acid group and B is the radical of an ortho-nitrodiarylamine which contains at least one sulphonic acid and/or at least one carboxylic acid group. The dyes are made by condensing in a molecular ratio of substantially 1 : 1 : 1, a trihalogen-1 : 3 : 5-triazine, an ortho-nitrodiarylamine containing at least one sulphonic acid group and/or at least one carboxylic acid group and a dyestuff of the formula <FORM:0895399/IV (c)/2> where R is a benzene radical which contains an acylatable amino group and may be further substituted and Z has the value above. Examples are given. The dyestuffs dye and print wool, silk and natural or regenerated cellulose fibres in conjunction with an alkali and heat treatment greenish shades.
