To provide an optical functional layer forming composition for obtaining an optical film having no fault by foreign substance and having sufficient abrasion resistance and optical characteristics and further to provide the optical film, an antireflection film and a polarizing plate.

The optical functional layer forming composition includes a light translucent resin, light translucent resin particulates and a fluoroaliphatic group-containing polymer. In the optical functional layer forming composition, the fluoroaliphatic group-containing polymer is at least one kind expressed by general formula (1).
