Kind Code:

A1

Abstract:

A composition which can impart excellent water repellency and oil resistance to paper even when dried at a low temperature in a short time. The composition comprises: a fluorocopolymer (A) obtained by polymerizing a polyfluoroalkylated (meth)acrylate, vinylidene chloride, and a compound represented, for example, by [CH¿2?=C(R)COO-CH¿2?-CH(OH)-CH¿2?N?+¿(CH¿3?)¿3? X?-¿ (R is hydrogen or methyl and X?-¿ is a counter ion)] with the aid of an oleophilic polymerization initiator (E) whose solubility in 100 g of water is less than 3 g; a non-fluorochemical surfactant (B); a medium (C); and a water-soluble polymer (D) (polyacrylamide, polyvinyl alcohol, or starch).
