Being the antireflection film which is laminated on the acid resisting null transparent backing material it can making use of the antireflection film and the replica membrane which can production method of the antireflection film and the antireflection film, making use of the mold

摘要

PPROBLEM TO BE SOLVED: To provide an antireflection film that has satisfactory antireflection performance to light in the visible range of wavelengths without coloring under the radiation of light in the visible range of wavelengths, and can be manufactured by a simple method. PSOLUTION: The antireflection film is laminated on a transparent substrate. The antireflection film includes a transparent resin and microparticles dispersed in the transparent resin. The microparticles have an average center distance in the range of 50 to 800 nm between nearest neighbor particles. The microparticles in the antireflection film have an amorphous structure of array. The surface of the antireflection film is shaped into recesses and projections having an average projection height in the range of 40 to 500 nm. PCOPYRIGHT: (C)2009,JPO&INPIT
