Abstract

An additive for paper production, comprising an amphoteric polymeric electrolyte having as an essential component thereof a structural unit represented by the following general formula I:

(see fig.I) wherein n is an integer in the range of 1 to 5, R1, R2, and R3 are independently hydrogen atom or an alkyl group, R4 is hydrogen atom, an alkyl group, or a hydroxyalkyl group, and a and b are jointly relative numerals such that the a/b ratio is in the range of 0.2 to 45.0), having at least part of the amino group of said amphoteric polymeric electrolyte neutralized, and possessing a cation equivalent amount (Cv) in the range of 1.0 to 15.0 meq/g, an anion equivalent amount (Av) in the range of 0.1 to 7.0 meq/g, and a Cv/Av ratio in the range of 0.2 to 45Ø
