<p>The present invention relates to a white, porous, single-layer polyester film comprising a polyester resin, particles of a noncrystalline polymer which has a heat deformation temperature higher than the temperature of the drawing process of said film by at least 10° C. and is not miscible with the polyester resin, inorganic particles and a whitening agent. The inventive single layer film has sufficient process stability as well as good optical properties, and thus is useful as a film for use in printing, labeling, electronics and display applications.</p> |
