    摘要: A composition for formation of an antireflection film having an excellent etching resistant characteristic and ability to prevent reflection of short-wavelength light (absorption ability of short-wavelength light) as well as excellent time dependent stability, and an antireflection film in which the same is used, are provided. A composition for formation of an antireflection film including a siloxane compound having a light-absorbing group and a crosslinking group, the siloxane compound being blocked with a capping group, is provided. By thus blocking the siloxane compound with a capping group, time dependent stability can be improved without deteriorating etching resistance, and ability to prevent reflection.
