Abstract: An oil-resistant agent and an oil-resistant composition, which are capable of imparting excellent oil-resistance to paper. The oil-resistant composition contains a polysaccharide (1) and an oil-resistant polymer (2). The polysaccharide (1) is preferably starch. The oil-resistant polymer (2) preferably has (a) a repeating unit formed from an acrylic monomer that has a long-chain hydrocarbon group having 7-40 carbon atoms, and (b) a repeating unit formed from an acrylic monomer that has a hydrophilic group. A polyvinyl alcohol or glucose may be present as an additive.

Abstract: A non-fluorinated copolymer composition containing (1) a fluorine-free copolymer and (2) acetylene alcohol. The non-fluorinated copolymer (1) has a repeating unit formed from (a) an acrylic monomer having a long-chain hydrocarbon group having 7 to 40 carbon atoms; and a repeating unit formed from (c) an acrylic monomer having an olefinic carbon-carbon double bond and an ion donating group. Also disclosed is an oil-resistant agent containing a fluorine-free composition including (1) a fluorine-free copolymer, and (2) an acetylene alcohol, wherein the fluorine-free copolymer (1) has a repeating unit formed from (a) an acrylic monomer having a long-chain hydrocarbon group having 7 to 40 carbon atoms; an oil-resistant agent kit; a method for producing the fluorine-free copolymer; an oil-resistant paper; and a method for eliminating foam during treatment of paper with the fluorine-free copolymer composition.
