The provided resin composition for an optical material contains: a polymer (A) obtained by using (meth)acrylic acid or an alkyl(meth)acrylate; and a polyester resin (B). The polyester resin (B) is a polyester resin (B1) that has, in a main chain thereof, an aromatic ring-containing structural unit and has a number average molecular weight of 300 to 5,000, and each end of the main chain is capped with a monocarboxylic acid residue or a monoalcohol residue."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Resin composition for optical material, optical film, and liquid crystal display device","description":"An object of the present invention is to provide a resin composition that exhibits only a small change in birefringence due to external force and can be suitably used for production of optical members","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9690013","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
