Abstract
The present invention provides an anti-reflective material with good the stainproofing properties, wherein dust and fingerprints do not readily adhere to the surface and can be easily wiped off when adhered, the anti-reflective material being provided with a stainproofing layer having excellent durability of its stainproofing effect. In an anti-reflective material comprising a transparent substrate and a low-refractive index layer and a stainproofing layer laminated in order on the transparent substrate, the low-refractive index layer is a silica film formed by the sol-gel method, and the stainproofing layer contains at least a perfluoroalkyl ether compound.
