剤が求められていた。In order to solve the above problems, various cationic polymers, for example, condensates of dicyandiamide and formalin, condensates of polyamines such as ethylenediamine and diethylenetriamine and dicyandiamide, reaction products of secondary amines and epichlorohydrin, etc. Polyamine sulfonic acids and the like are known. In addition, in recent years, it has been disclosed that polydimethyldiallylammonium chloride is used to treat objects dyed with reactive dyes (Japanese Patent Publication No. 1983).
-9999, JP-A-56-128382). However, the polymers used in these products are all low-molecular weight substances, and the chlorine fastness of dyed objects that undergo this treatment decreases, so there is a need for dye fixatives with better chlorine fastness. was.

に処理後に染色物の変色も認められる欠点がある。As a result of various studies conducted by the present inventors regarding the fixing agent used in the above-mentioned post-treatment, we found that a specific polymer having a molecular weight above a certain level lowers the chlorine fastness compared to conventionally known dye fixing agents. The present invention has been completed based on the discovery that it has the effect of significantly improving various fastnesses without causing any problems, and is extremely effective as this type of adhesive. In this case, if the molecular weight is below a certain level, there is a drawback that a decrease in chlorine fastness is observed, and discoloration of the dyed product is also observed after treatment.
