PURPOSE:To obtain the titled copolymer which can give a dyed product excellent chlorine fastness, washing resistance, light fastness, etc., and is useful as a dye fixing agent, by copolymerizing a specified diallylamine compound with a triallylamine compound. CONSTITUTION:A diallylamine compound (A) of formula I (wherein R1-2 are each H or CH3, R3-4 are each H, a 1-18C alkyl, cycloalkyl or benzyl and X is a counter ion of an acid) is copolymerized with a triallylamine compound (B) of formula II (wherein R5 is R1) and, optionally, monomers (C) other than the above (e.g., vinylpyrrolidone) at 30-100 deg.C for 3-48hr in the presence of 0.1-7wt% radical polymerization initiator (e.g., ammonium persulfate) at a molar ratio of A/B=99.99-98/0.01-2 or A/B/C=99.99-68/0.01-2/0-30.
