EASILY-ADHESIVE POLYESTER FILM
Document Type and Number:
WIPO Patent Application WO/2019/058999
Kind Code:
A1
Abstract:
[Problem] To provide an easily-adhesive polyester film that is excellent for all aspects regarding transparency, anti-blocking properties, adhesion to a hard coat layer or the like required at a high level in various optical applications, and low interference properties for inhibition of iridescent irregularity, that has high lubricity, that is easy to handle when being manufactured or in steps subsequent to a step for producing a polarizing plate for a liquid crystal display device, and that can be suitably used in optical applications. [Solution] This easily-adhesive polyester film has, on at least one surface of a polyester film, a coating layer containing a polyurethane resin having a polycarbonate backbone and a polyester resin having a naphthalene backbone, wherein, when the contained amount a of the polyurethane resin component, the contained amount b of the polyester resin component having a naphthalene backbone, and the total amount c of the other components are plotted in a triangular diagram, where the total solid content of the coating layer is 100 mass%, a, b, and c are within a region surrounded by specific four straight lines.
