Abstract
A treatment for paper, containing (A) a fluorine-containing polymer comprising repeating units derived from a fluorine-containing monomer (a) represented by the general formula (I): CH2═C(—X)—C(═O)—Y—(CH2)m-Z-(CH2)n—Rf (I) wherein X is hydrogen, methyl, fluoro, chloro, CFX1X2 (wherein X1 and X2 are each hydrogen, fluoro, or chloro), or the like; Y is —O— or —NH—; Z is —S—, —SO—, or —SO2—; Rf is fluoroalkyl having 1 to 6 carbon atoms; m is 1 to 10; and n is 0 to 10.
