PURPOSE:To obtain a slippery film having a rough surface on one side and a flat surface on the other side and exhibiting excellent flatness and slipperiness by laminating a plain resin layer and/or a resin layer containing inorganic particles on one surface of a layer composed of a styrene polymer having syndiotactic structure. CONSTITUTION:The objective film having a rough surface on one a side and flat surface having surface roughness of 0.001-0.02mum on the other side and having a static frictional coefficient of 0.3-1 can be produced by laminating a layer composed of a plain resin and/or a resin containing inorganic particles (especially a syndiotactic styrene polymer containing inorganic fine particles having an average particle diameter of 0.01-3mum) to a surface of a drawn film composed mainly of a styrene polymer having syndiotactic structure (especially a polymer having residual aluminum content of <=3,000ppm, residual titanium content of <=10ppm and residual styrene monomer content of <=7,000ppm) during the production process of the drawn film (especially before or after the drawing process or after the thermal treatment). |
