Further, the invention also relates to an optical laminate, a polarizing plate, and an image display device each using the optical film. The optical film of the invention advantageously has not only high solubility in solvents but also a high level of transparency since the polymers used in the optical film are compatible with each other. Further, wavelength dispersion of the birefringence of the optical film can be controlled by merely changing a ratio of polymers."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical film and method for production thereof","description":"The invention relates to an optical film containing polymers having different repeating units, and methods for production thereof.
