Abstract

A white porous film, which comprises a polyester resin, a hydroxyphenyl triazine-based UV stabilizing agent, amorphous polymer particles which are immiscible with a polyester, first inorganic particles having a refractive index of 2.0 or more, and second inorganic particles having a refractive index of 1.7 or less, has improved optical properties such as whiteness, masking ability, reflectance, and UV-resistance and it is useful as a functional film for use in printing, labeling, electronics, and display applications.
