Abstract
An anti-reflection film (X) of the present invention includes a laminated structure including a substrate (11), a hard coat layer (12), and an anti-reflection layer (13), and a luminous reflectance of the anti-reflection layer (13) side is 2% or less. The anti-reflection layer (13) includes a surface (13a) having a coefficient of kinetic friction of 0.3 or less and a coefficient of static friction of 0.3 or less. In addition, in the anti-reflection film (X), after a rubbing test performed on the surface (13a) using steel wool #0000 as a rubbing material under conditions of a load of 200 g/cm2, a rubbing stroke length of 10 cm, and reciprocations of 1000 times, a difference of the haze value (%) after the rubbing test from the haze value (%) before the rubbing test is 0.1 or less. Such an anti-reflection film is suitable for achieving high scratch resistance together with high anti-reflective properties.
