Abstract

The invention comprises water-insoluble monoazo dyes of formula <FORM:1036843/C4-C5/1> wherein the group R-NH-SO2 is in meta or para position to the azo group, R is a hydrogen atom, an alkyl, cycloalkyl, hydroxyalkyl, alkenyl or acetyl radical or an aryl radical which may be substituted by non-ionic groups and the benzene nuclei B and C may be substituted by alkyl or alkoxy groups or halogen atoms. The dyes are prepared by coupling a diazotized 3- or 4-sulphonamido-aniline in substance or on the fibre (see Divisions D1-D2) with a 5-(21:31-hydroxynaphthoylamino)-benzimidazolon preferably in the presence of a surface active agent. The physical characteristics of the dye may be improved by heating an aqueous paste of the dye or by treating the paste or dry dye with a solvent such as pyridine dimethylformamide, N-methylacetamide and o-dichlorobenzene. The dyes may be used to colour rubber, natural and synthetic resins, particularly polyvinyl chloride in red and brown shades. Many examples are specified.
