PROBLEM TO BE SOLVED: To provide a raw material compound for producing a novel reactive dye having a triazine and a specific vinyl sulfone group, and a method for producing the same. A free acid form represented by the following formula: [Wherein, X represents fluorine, chlorine or bromine, R 2 represents alkyl, Cl, Br, alkoxy or COOH; Represents 0 to 1, j represents 0 to 2, r represents 2 to 3, w represents a direct bond or a bonding group, and D represents a group of an organic dye. Z is -C H = CH 2, -CH 2 -CH 2 -OSO 3 H, CH 2 - CH 2 -S 2 O 3 H, -CH 2 -CH 2 -O-CO-C H 3, -CH 2 -CH 2 -OPO 3 H 2 or -CH 2 —CH 2 —OH. The method for producing a starting compound represented by the following formula for producing a reactive dye, which shows an improved fixation yield in dyeing represented by the following formula: Wherein R 2 , i, j, r and Z have the meaning described above. |
