摘要：
Cellulose fiber materials are dyed with a dye represented by a free acid of the formula, ##STR1## wherein W.sub.1 and W.sub.2 are independently a direct linkage or a bridging group, Q.sub.1 and Q.sub.2 are independently a fiber-reactive group, A.sub.1 and A.sub.2 are independently a phenylene or naphthylene group unsubstituted or substituted, D is a residue of 1-amino-8-naphthol mono- or di-sulfonic acid, m and n are independently 0, 1 or 2, provided that they satisfy the formula, 0
