Provided is a water-resistant/oil-resistant agent for paper that exhibits little foam formation and excellent product stability. The water-resistant/oil-resistant agent for paper comprises: (1) (a) a fluorine-containing monomer that has a fluoroalkyl group and that is represented by general formula (1) (General formula (1): CH2=C(-X)-C(=O)-Y-Z-Rf, , in which X is a hydrogen atom, a linear or branched alkyl group having 1-21 carbon atoms, a fluorine atom, a chlorine atom, a bromine atom, an iodine atom, or the like; Y is -O- or -NH-. Z is an aliphatic group having 1-10 carbon atoms, an aromatic group having 6-10 carbon atoms, a cycloaliphatic group, or the like; and Rf is a linear or branched fluoroalkyl group having 1-6 carbon atoms.) and (b) a fluorine-containing copolymer that includes, as a necessary component, a repeating unit derived from a (meth)acrylate monomer containing no fluorine atoms; and (II) a polypropylene glycol compound. L'invention concerne un agent résistant à l'eau/résistant à l'huile pour papier qui présente peu de formation de mousse et une excellente stabilité de produit. L'agent résistant à l'eau/résistant à l'huile pour papier comprend : (I) (a) un monomère contenant du fluor qui comporte un groupe fluoroalkyle et qui est représenté par la formule générale (1) (formule générale (1) : CH2=C(-X)-C(=O)-Y-Z-Rf [dans la formule, X est un atome d'hydrogène, un groupe alkyle linéaire ou ramifié comportant 1 à 21 atomes de carbone, un atome de fluor, un atome de chlore, un atome de brome, un atome d'iode, ou similaire. Y est -O- ou -NH-. Z est un groupe aliphatique comportant 1 à 10 atomes de carbone, un groupe aromatique comportant 6 à 10 atomes de carbone, un groupe cycloaliphatique, ou similaire. Rf est un groupe fluoroalkyle linéaire ou ramifié comportant 1 à 6 atomes de carbone.]) et (b) un copolymère contenant du fluor qui inclut, comme composant nécessaire, un motif répété dérivé d'un monomère de (méth)acrylate ne contenant pas d'atomes de fluor; et (II) un composé polypropylène glycol.
