PURPOSE: To obtain a strong dyed product generating no variation of hue even performing a post-finishing process with a processing agent formable crosslinking bond with cellulosic fibers by dyeing cellulosic fibers material with a specific metallic formazan compound. CONSTITUTION: A dyed finished product having slight variation of hue and excellent in color fastness to light, resistance to hot pressing, sweat resistant color fastness to light, chlorine resistant fastness is obtained by dyeing cellulosic fiber material with a metallic formazan compound of the formula [A is phenylene or naphthylene; B is an alkyl, an alkenyl, a phenyl, a naphthyl or a hetero ring; Me is a metal ion of 27-29 atomic number; X is O or the like; Y is a lower alkoxy, phenoxy or the like; Z is a soluble group; (m) and (n) are each 0 or 1-3 and its total is 1-3; D is benzene or naphthalene; Q is SO2 CH= CH2 or SO2 CH2 CH2 L (L is a group removable with an alkali); R is H or a lower alkyl] and subjecting to a finishing treatment with a fiber reactive processing agent. By the process, a reactive dye can be used in a resin processing field. |
