PROBLEM TO BE SOLVED: To impart oil repellency to a breathable film, which is composed of a porous molded product constituted by binding fine particles of ultrahigh molecular weight polyethylene to one another, without significant reduction in breathability.SOLUTION: A breathable film has a surface coated with an oil repellent agent. The linear fluorine-containing hydrocarbon group contained in the oil repellent agent is represented by (1)-RCFCHCFor (2)-RCF, and the porous body is constituted by binding fine particles of ultrahigh molecular weight polyethylene to one another, to form a breathable film imparted with oil repellency. In the formulae, each of Rand Ris independently 1-12C alkylene or phenylene. |
