표면 반사율이 낮고, 열성형성이 우수함과 함께 내찰상성도 양호한 적층체인 반사 방지 필름 등을 실현한다. 전술한 과제는, 열가소성 수지를 포함하는 기재층과, 기재층의 적어도 한쪽의 표면 상에 적층되고, 기재층의 굴절률보다도 높은 굴절률을 갖는 고굴절률층을 갖는 반사 방지 필름으로서, 고굴절률층이, 플루오렌계 다이올, 아이소사이아네이트, 및 (메트)아크릴레이트 유래의 유레테인 (메트)아크릴레이트와, (메트)아크릴레이트를 포함하는 수지 재료의 중합체를 포함하는, 반사 방지 필름에 의해 해결되었다. The present invention enables the achievement of: an antireflection film which is a multilayer body that has low surface reflectance, while having excellent heat moldability and good scratch resistance; and the like. The above are achieved by means of an antireflection film which comprises a base material layer that contains a thermoplastic resin and a high refractive index layer that is superposed on at least one surface of the base material layer, while having a refractive index that is higher than the refractive index of the base material layer, and which is configured such that the high refractive index layer contains a fluorene diol, an isocyanate and a polymer of a resin material that contains a (meth)acrylate and a urethane (meth)acrylate derived from a (meth)acrylate.
