Abstract
A reactive dye composition containing a dye mixture comprising 60 to 97 wt. % of C.I. Reactive Orange 16 and 40 to 3 wt. % of C.I. Reactive Orange 7, and 5 to 100 parts by weight per 100 parts by weight of said dye mixture of a naphthalenesulfonic acid/formaldehyde condensate having a sulfonation degree of 100 to 200%, which is very readily soluble in water and an aqueous alkaline solution and useful for dyeing cellulose fibers with a high color yield.
