| 摘要 |
The instant invention is directed to a dyed cellulosic material which has been treated with 0.1 to 5%, by weight, based on the weight of said material, of a polymer containing: (A) 50% to 90%, by weight, based on the total weight of the polymer, of selected cationic mer units; (B) 10% to 50%, by weight, based on the total weight of the polymer, of selected reactive mer units; and (C) 0 to 25%, by weight, based on the total weight of the polymer of selected inert mer units. The instant invention is also directed to a process for producing improved wet fast dyed cellulosic material.
