| abstract | The invention discloses a class of 4,4'-diaminostilbene-2,2'-disulfonic acid derivatives represented by formula A. The 4,4'-diaminostilbene-2,2'-disulfonic acid derivatives of the present invention can improve the fastness and color fixation rate of fluorescent whitening agents, and the dyeing temperature is about 60°C, which is much lower than that of traditional The dyeing temperature of fluorescent whitening agent can reduce energy consumption and dyeing cost. In formula A, R 1 is -NH 2 ; it is selected from "C 1 ~ C 4 alkyl, C 1 ~ C 4 alkyl substituted by 1 ~ 2 hydroxyl groups, and 1 ~ 2 -NH 2 substituted by a carboxyl substituted C 1 ~C 4 alkyl"group;anilino; the hydrogen on the benzene ring is replaced by 1~2 selected from "-SO 3 Na, -COCH 3 and halogen atoms" An anilino group substituted by a group; or, a C 3 ~C 5 saturated cyclic amine group containing 0 to 2 heteroatoms selected from O and S. R2 is |
