Title:
光学用ポリエステルフィルム
Document Type and Number:
Japanese Patent JP7279288
Kind Code:
B2
Abstract:
The present invention pertains to an excellent optical polyester film comprising a polymeric primer layer formed on one or both surfaces of a substrate film, wherein the polymeric primer layer has excellent adhesiveness due to the application of a carboxylic group-containing acrylic resin and a polyalkylene oxide resin, as well as a thermosetting coating liquid crosslinked using at least one crosslinking agent selected from among carbodiimide, isocyanate, and melamine compounds, and transparency is maintained by preventing oligomer precipitation that results from heat treatment, thus allowing the optical polyester film to be effectively used in a coating process, which includes a heating process, for optical functionality.
