    Abstract: A polyolefin-based porous film made of a polyolefin-based resin composition has a pore surface area of 35.0 to 42.0 m 2 /g and birefringence of 2.0x10 -2 to 4.0x10 -2 .
    A method for producing a polyolefin-based porous film includes an (A) step: a raw fabric forming step for forming a non-porous raw fabric from a polyolefin-based resin composition, a (B) step: an MD cold stretching step for cold stretching the non-porous raw fabric obtained in the (A) step at a temperature of -20°C to (Tm-30) °C (Tm is a melting point (°C) of the non-porous raw fabric) in an extruding direction (MD) of the raw fabric to make the raw fabric porous; wherein a birefringence of the non-porous raw fabric obtained in the (A) step is 3.0x10 -2 or more, and a pore surface area of the obtained polyolefin-based porous film is 42.0 m 2 /g or less.

    Abstract: Provided is an anti-fogging coated transparent article including an anti-fog film, the anti-fog film being a single-layer film containing a water-absorbent resin, a hydrophobic group, and a metal oxide component. The hydrophobic group is a chain or cyclic alkyl group having 1 to 30 carbon atoms, preferably a linear alkyl group having 6 to 14 carbon atoms, in which at least one hydrogen atom is optionally substituted by a fluorine atom. The hydrophobic group is bonded directly to a metal atom of the metal oxide component. The anti-fog film contains, for example, the metal oxide component in an amount of 0.01 to 60 parts by mass and the hydrophobic group in an amount of 0.05 to 10 parts by mass per 100 parts by mass of the water-absorbent resin. The water-absorbent resin is, for example, polyvinyl acetal.
