Abstract: An oil-resistant agent composition which contains (1) a hydrocarbon group-containing polymer and (2) an amphoteric polyacrylamide polymer, and which is capable of imparting paper with excellent oil resistance. The hydrocarbon group-containing polymer has (a) a repeating unit that is formed from an acrylic monomer which has a long-chain hydrocarbon group having 7 to 40 carbon atoms and (b) a repeating unit that is formed from an acrylic monomer which has a hydrophilic group. Preferably, the oil-resistant agent composition additionally contains an anionic polyacrylamide polymer. Also disclosed is an oil-resistant agent kit including a liquid containing the oi-resistant agent composition, a method for producing oil-resistant paper which includes adding the oil-resistant agent composition to a paper constituent material, pulp or pulp slurry, as well as an oil-resistant paper.
