| 发明名称 | Air-permeable sheet imparted with oil repellency | ||
| 摘要 | 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 —R1C5F10CH2C4F9 or —R2C6F13, where R1 and R2 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. | ||
