PURPOSE: A novel dye mixtures of fiber-reactive azo dyes with which color effectiveness is significantly improved over than the average color effectiveness of respective dyes in dye mixture due to its water solubility, thereby increase in build-up characteristics, and improvement in water fastness, light fastness, alkali sweat fastness, and fastness regarding pleating etc. can be achieved, is provided. CONSTITUTION: A fiber-reactive azo dye mixtures containing the following formula(1) of yellow dye are usefully applied to dyeing hydroxy- and/or Carbonari-containing fiber material, particularly cellulose fiber such as cotton and filament viscose, and synthetic polyamide fiber. In the formula(1), Y¬1 represents vinyl or substituted ethyl at its beta position by alkali removable substituent, R¬1 represents hydrogen, chloride, alkyl having 1-4 of carbon atoms, alkoxy having 1-4 of carbon atoms, or sulfur, R¬2 represents hydrogen, alkyl having 1-4 of carbon atoms or alkoxy having 1-4 of carbon atoms, R¬3 represents hydrogen, alkyl having 1-4 of carbon atoms, or alkoxy having 1-4 of carbon atoms, or sulfur, and R represents amino or alternatively substituted alkyl having 1-6 of carbon atoms.
