| 摘要 |
A functional composite film having one or more combinations of an inorganic layer and a substrate organic layer on one surface thereof, and on the opposite surface thereof, having a light diffusion layer obtained by dispersing a light diffusion agent in a binder formed using a graft copolymer which: has an acrylic polymer as the main chain thereof; as a side chain thereof, has a urethane polymer with an acryloyl group on one end thereof, and/or a urethane oligomer with an acryloyl group on one end thereof; has a molecular weight of 10,000-3,000,000; and constitutes an acrylic equivalent of 500 g/mol or more. Also, a wavelength conversion film using the same. As a result, provided are a functional composite film and a wavelength conversion film which exhibit favorable light diffusion performance and light transmission properties. |
