    摘要： A water- and oil-repellent composition for a nonwoven fabric, which comprises (1) a fluorine-containing water- and oil-repellent agent and (2) a sizing agent and is water-based, can impart good alcohol repellency, water pressure resistance, and antistatic properties to an object to be treated, such as a nonwoven fabric. The water- and oil-repellent composition for a nonwoven fabric does not contain a carbodiimide compound and may contain at least 20 wt% of water with respect to the water- and oil-repellent composition. The active ingredient of the sizing agent may include an alkylketene dimer and/or an alkenylketene dimer. The water- and oil-repellent composition may further contain an antistatic agent and a penetrant. A treated substrate is preferably a nonwoven fabric.

    摘要： The present invention provides a softening agent composition that includes (1) a silicone polymer, (2) a water-repellent polymer, (3) an emulsifier, and (4) a liquid medium that is water or a mixture of water and an organic solvent. The water-repellent polymer is preferably manufactured by polymerizing, in the presence of the silicone polymer, a monomer that constitutes the water-repellent polymer. The water-repellent polymer is preferably at least one selected from the group consisting of fluorine-containing polymers and non-fluorine-containing polymers.

    摘要： Provided is a coating composition that can enables to form a coating film having an excellent antifouling property using a fluorine-containing polymer having repeating units derived from (a) a fluorine-containing monomer, (b) a fluorine-free non-crosslinkable monomer, and (c) a fluorine-free crosslinkable monomer, wherein the fluorine-containing monomer (a) is a compound represented by formula: CH 2 =C (-X) -C (=O) -Y-Z-Rf ... (a-I) wherein X is a hydrogen atom, a monovalent organic group or a halogen atom, Y is -O- or -NH-, Z is a direct bond or a divalent organic group, Rf is a fluoroalkyl group having 1 to 20 carbon atoms, and wherein the fluorine-free non-crosslinkable monomer (b) comprises (b1) a cyclic hydrocarbon group-containing monomer and (b2) a low Tg monomer, a homopolymer of which has a glass transition temperature (Tg) of lower than 0°C.
