A porous film comprises a polyolefin resin, a filler and an ester of dipentaerythritol having from 0 to 70% residual OH groups, based on the number of OH groups of unesterified dipentaerythritol. The film can be used as a liquid impermeable back sheet of absorbent sanitary articles, such as diapers, which comprise a liquid permeable surface sheet, a liquid absorber and a liquid impermeable back sheet; said liquid absorber being interposed between said liquid permeable surface sheet and said liquid impermeable back sheet.
