Abstract

Disclosed are a resin solution containing a polyester of a specific structure, an optical film and a method for producing an optical film. Also disclosed are an optical laminate, a polarizing plate and an image display device, each using the optical film. The polyester is preferably a polycondensation product of a bisphenol and an aromatic dicarboxylic acid. It is more preferable that the polyester does not contain a halogen atom. Since the polyester is highly soluble in a solvent, the optical film is excellent in productivity, while being reduced in burden on the environment during production.
