Document Type and Number:
Japanese Patent JP6148058
Kind Code:
B2
Abstract:
Provided is an air-permeable sheet imparted with oil repellency, having a surface coated with an oil-repellent agent. The oil-repellent agent contains a linear fluorine-containing hydrocarbon group represented by -R 1 C 5 F 10 CH 2 C 4 F 9 or -R 2 C 6 F 13 , where R 1 and R 2 are each independently an alkylene group having 1 to 12 carbon atoms or a phenylene group. The air-permeable sheet is a resin sheet having air permeability in a thickness direction of the resin sheet, the resin sheet is a non-porous sheet having two or more through holes formed to extend in the thickness direction, and the through holes are straight holes extending straight through the resin sheet. This air-permeable sheet is imparted with oil repellency without significantly reducing its air permeability.
