Abstract
The present invention provides an antireflection film for transfer that can be transferred to the surface of plates or other less-flexible articles to form an antireflection layer with a uniform thickness that not only provides a high antireflection effect on a light in the visible light range but also offers a high solvent resistance. The present invention also provides an antireflection-treated article. An antireflection film for transfer comprising a support (); an antireflection layer () comprising a low refractive index layer () disposed on the support () and a high refractive index layer (b) disposed on the low refractive index layer and having a higher refractive index than the refractive index of the low refractive index layer; and an adhesive layer () on the antireflection layer (), wherein the high refractive index layer () contains metal oxide fine particles, and a photopolymerization initiator and/or a photosensitizer, the adhesive which constitutes the adhesive layer () is an active energy ray-curable adhesive and the high refractive index layer () is impregnated with a portion of the adhesive, and the support () is releasable from the antireflection layer(1).
