Abstract:
Provided is an antireflective member that has a water- and oil-repellent layer on a multi-layered antireflective layer and is capable of exhibiting excellent surface lubricity, water- and oil-repellent properties, and durability. The surface of the multi-layered antireflective layer on a base material has a root-mean-square surface roughness of 0.8 nm to 2.0 nm. The water- and oil-repellent layer has a thickness of 1 to 30 nm and is a cured product of water- and oil-repellents having as principal components a fluorooxyalkylene group-containing polymer modified organosilicon compound with the numerical average molecular weight of 4,500 to 10,000 of a fluoropolymer part and/or partial hydrolysis condensate thereof.
