| 摘要 |
The present invention can obtain a porous substrate having a moisture-permeable, waterproof film and a water-repellant, oil-repellant treated surface that has favorable water-repellant, oil-repellant properties and washing durability, has suppressed permeation of a coating liquid for forming the moisture-permeable, waterproof film, and has suppressed delamination of the moisture-permeable, waterproof film. This water-repellant, oil-repellant composition contains: a copolymer (A) having 60-95 mass% of a unit that is on the basis of a monomer having an RF group having no greater than 6 carbon atoms, and 5-40 mass% of a unit that is on the basis of vinylidene chloride; a copolymer (B) having 50-95 mass% of a unit that is on the basis of a halogenated olefin and 5-50 mass% of a unit that is on the basis of a monomer having a cross-linkable functional group; and a medium (C). The proportion of copolymer (A) is 70-90 mass%, and the proportion of copolymer (B) is 10-30 mass%. |
