PURPOSE: Provided is a fiber-reactive dye having a specific chemical structure with a very high color strength, good rinsing characteristics, and a high levelness even when the bath ratio is very low by using. CONSTITUTION: The dye is represented by formula(2) £wherein F is a residue of a monoazo-, disazo-, or polyazo dye, a residue of an induced heavy metal complex dye, or the like; Rx is H, a halogen, cyano, or the like; n is 1 or 2; Q is a group of formula(1) (wherein Rz is H, a halogen, hydroxy, 1-4C alkoxy, or the like; W is alkyl-SO2-Y, or the like; A is 0 or 1; and B is 1 or 2 provided A+B is 2); V is a direct bond, alkylene, (substituted) arylene, or the like; y is 0, 1, or 2; z is 1 or 2; when y=2, then h is nitrogen and when y=1, then h is -NH-, a direct bond, or the like; and Y is vinyl or an ethyl group β- substituted by an alkali-separable substituent|.
