There are used a substituted bis(trifluorovinyl)benzene compound represented by general formula (1); and a method for producing a substituted bis(trifluorovinyl)benzene compound, comprising the step of reacting in the presence of a catalyst (such as palladium) a bishalobenzene derivative represented by general formula (3) and a compound obtained by reacting 1,1,1,2-tetrafluoroethane, a zinc halide, and an organolithium compound and represented by general formula (4), to thereby obtain a substituted bis(trifluorovinyl)benzene compound represented by general formula (1).

Abstract: The present invention is an anti-glare anti-reflection hard coating film which is capable of providing excellent anti-glare properties and anti-reflection properties, while being suppressed in glare if used in various displays, thereby enabling the achievement of good visibility, and which is also applicable as a film for surface protection. An anti-glare anti-reflection hard coating film includes a substrate in the form of a transparent film; and an anti-glare layer and an anti-reflection layer, which are sequentially arranged on one surface of the substrate in this order from the substrate side. The anti-glare layer has a thickness of 3-15 ?m; and the anti-reflection layer has a thickness of 50-150 nm. The anti-glare layer is a cured product obtained by curing a resin composition that contains an active energy ray-curable resin; and the resin composition contains silica particles that have a volume average particle diameter of 0.3-0.9 ?m.
