Provided are a fluorine-free soil resistant agent and a soil resistant treatment method which give excellent water-repellency and excellent antifouling property to a substrate, especially a carpet. The soil resistant agent contains (1) a fluorine-free copolymer having (a) a repeating unit formed from an acrylic monomer having a hydrocarbon group containing 7 to 40 carbon atoms, and (b) a repeating unit formed from an acrylic monomer having a hydrophilic group, and (2) water or a mixture of water and an organic solvent dispersing the fluorine-free copolymer (1). A method of treating the substrate, includes applying the soil resistant agent to the substrate.

Method of treating substrate

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.

Oil-resistant agent for paper

A composition including at least one compound having a perfluoropolyether group and a curable site, wherein in a molecular weight distribution curve in gel permeation chromatography measurement, the following formula is satisfied: M2/M1&#x2264;3.5, wherein M1 is a molecular weight at a main peak, and M2 is a molecular weight at 25% intensity of an intensity of the main peak on a higher molecular weight side than M1. Also disclosed is a curable composition containing the composition and a method for producing the curable composition.
