Composition of mixed benzensulfonamido anthraquinone dyes and linear polyester material dyed therewith

A composition comprising two or more benzensulfonamido anthraquinone dyes, selected from those of the formula: STR1 wherein R is methyl, ethyl, hydroxyethyl, β-methoxyethyl or β-ethoxyethyl, R1 is hydrogen or methyl and R2 is hydrogen, methyl or methoxy, provided that in at least one of the selected dyes, R1 and R2 are both hydrogen. The mixture of dyes gives improved dye strength and brightness of shade and is useful for dyeing linear polyester material, particularly textile material, in shades of red, with excellent leveling and fastness properties.
