Amide-containing cationic copolymer is reacted with polyalkyleneimine in an aqueous medium to form a water-soluble cationic resin which is a treating agent useful for fibrous materials. The adduct of halohydrin to water-soluble cationic resin is a water-soluble cationic thermosetting resin and is also useful for treating fibrous materials. The treating agent has excellent retention ability to fiber, drainage property and storage stability and remarkably improves the retention of fillers and wet and dry strength of paper.
