Abstract
A composition for a low refractive film, said composition comprising 10 parts by weight of a polysiloxane and 3 to 150 parts by weight of a volatile hydroxyalkylsilane. Based on the polysiloxane composition, films can be produced having a porous polysiloxane network and exhibiting a low refractive index of 1.4 or less and dielectric constant of 1.5 or less.
