Abstract
Official abstract text for this publication.
A white porous polyester film of the present invention comprising a polyester-based monopolymer/copolymer blend, a crystalline polymer resin which is not miscible with a polyester and has a heat deformation temperature of 90° C. or higher, inorganic particles, a whitening agent, and a stabilizing agent has improved optical properties, and thus is useful as a film for use in printing, labeling, electronics, and display applications.
First claim
Opening claim text (preview).
What is claimed is: 1. A white porous polyester film comprising a blend of a polyester-based monopolymer and a polyester-based copolymer; a crystalline polymer resin which is not miscible with a polyester and has a heat deformation temperature of 90° C. or higher, wherein the crystalline polymer consists of a syndiotactic polystyrene; inorganic particles; a whitening agent; and a stabilizing agent, wherein the amounts of the crystalline polymer resin and the inorganic pa…
