PURPOSE: To prepare a dye mixture which can dye cellulosic fiber materials and the like red brown, bluish gray, dark green or other colors to produce dyeings having high color density, sunlightfastness, and wetting fastness by using a mixture comprising specified three or more fiber-reactive dyes.

CONSTITUTION: This dye mixture comprises three to seven fiber-reactive materials selected form among compds. represented, e.g. by formula I [wherein M represents H or an alkali metal; (m) is 1 to 3; X represents cyanoamino, a 1-4C alkoxy or the like; R1 represents H, a 1-4C alkyl or the like; R2 represents H, sulfo, a 1-4C alkyl or the like; R3 represents H or a (substd.) 1-4C alkyl; R4 represents H, a (substd.) 1-4C alkyl or the like; Y represents ethyl having at the β-position a substituent which can be eliminated with the formation of a vinyl group], compds. represented, e.g. by formula II (wherein R7 represents H, a 1-4C alkyl or the like), and compds. represented, e.g. by formula III (wherein R8 represents H, methyl, nitro, sulfo or the like).
