Abstract: An oil-resistant agent for paper, which contains a non-fluorine copolymer that has a repeating unit formed from (a) an acrylic monomer having a long-chain hydrocarbon group with 7-40 carbon atoms and a repeating unit formed from (b) an acrylic monomer having a hydrophilic group. The oil-resistant agent for paper also contains a liquid medium that is composed of water and/or an organic solvent, preferably of water or a mixture (aqueous medium) of water and an organic solvent. The non-fluorine copolymer preferably has a repeating unit formed from (c) a monomer having an ion donor group in addition to the repeating units formed from the monomers (a) and (b). Also disclosed is an oil-resistant paper having an oil-resistant layer including the oil-resistant agent for paper, and starch or modified starch, on a surface of the paper as well as a method of treating paper.

Abstract: A fluorine-containing polymer including a repeat unit derived from a fluorine-containing monomer (A1) and a repeat unit derived from a hydrocarbon group-bearing fluorine-free monomer (A2). The fluorine-free monomer (A2) is preferably at least one monomer selected from (A2-1) R22—C(═O)—NH—R23—O—R21, (A2-2) CH2═C(—R32)—C(═O)—Y31—Z31(—Y32—R31)n, and (A2-3) X41N(H)r—R41. Also disclosed is a surface treatment agent containing (A) the fluorine-containing polymer and (B) a liquid medium, as well as a method for producing the surface treatment agent and a method for producing a treated substrate.

Abstract: A water- and oil-repellent agent including: (a) a fluorine-containing monomer represented by the general formula CH2═C(—X)—C(═O)—Y—Z—Rf [where X is a hydrogen atom, a monovalent organic group, or a halogen atom, Y is —O— or13 NH—, Z is a direct bond or a divalent organic group, and Rf is a fluoroalkyl group having 1-20 carbon atoms]; and (b) a fluorine-containing copolymer containing a repeating unit derived from nonyl(meth)acrylate. Also disclosed is a textile product including a fibrous substrate treated with the water- and oil-repellent agent.

Abstract: Provided is a water repellent composition which does not use a fluorine-containing monomer, especially a fluoroalkyl group-containing monomer. A water repellent composition which contains (1) (a) a polymer which has a repeating unit derived from an amide group-containing monomer that is represented by formula: (wherein R1 represents an organic residue having an ethylenically unsaturated polymerizable group; R2 represents a hydrocarbon group having 7-30 carbon atoms; and R3 represents a hydrocarbon group having 1-5 carbon atoms) in an amount of 2-100% by weight relative to the polymer, and (2) a liquid medium.
