Abstract: PURPOSE: Provided is benzothiazole-based dispersion-reactive dye, which reduces pollution, dose not contain hazardous amine and metals, can be used in acidic and neutral condition, and is excellent in washing-fastness and properties. CONSTITUTION: The benzothiazole-based dispersion-reactive dye represented by the formula 1 is produced by a process comprising the steps of: diazotizing 2-amino-5-(beta-acetoxy ethyl sulfone)benzothiazole or 2-amino-5-(beta-hydroxy ethyl sulfone)benzothiazole; preparing a coupling solution by dissolving a coupler in an acid mixture; mixing the diazotized 2-amino-5-(beta-acetoxy ethyl sulfone)benzothiazole and the coupling solution at 5-10deg.C and adding a base and separating the produced dye or mixing the diazotized 2-amino-5-(beta-hydroxy ethyl sulfone)benzothiazole and the coupling solution at 5-10deg.C and stirring at 80-90deg.C by using acetic anhydride. In the formula, R, R1, R2, and R3 are identically or differently hydrogen, alkyl, alkoxy, cyanoalkyl, or amino acetyl.
