A water repellent and oil resistant composition capable of imparting excellent water repellency and oil resistance to paper even under a condition of drying at a low temperature for a short time, is provided. n The composition comprising a fluorocopolymer (A) obtained by polymerizing a polyfluoroalkyl group-containing (meth)acrylate, vinylidene chloride and a compound of the formula [CH 2 ═C(R)COO—CH 2 —CH(OH)CH 2 N+(CH 3 ) 3. X − (R: a hydrogen atom or a methyl group, and X − : a counter ion)] or the like by means of a lipophilic polymerization initiator (E) having a solubility of less than 3 g in 100 g of water, a non-fluorine surfactant (B), a medium (C) and a water-soluble polymer (D) (a polyacrylamide, a polyvinyl alcohol or starch). |
