Embedded image Embedded image [Wherein R 1 and R 2 represent hydrogen, X 1 and X 2 represent chloro, substituted pyridinio, U represents a specific fiber reactive group, and T 1 and T 2 represent specific non-fiber reactive groups. However, the two * shown in [] Mark One is a bond and -U, the other represents a bond with -T 1, T 2. Further, T 2 is different from the T 1. ] |
