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). The anti-reflection layer (13) contains a curable resin, low-refractive-index particles, and nanodiamond particles. The anti-reflection layer (13) may further contain a fluorine-containing curable compound. Such an anti-reflection film is suitable for achieving high scratch resistance together with high anti-reflective properties.
Claims17
An anti-reflection film having a laminated structure comprising:
- a substrate;
- an anti-reflection layer comprising a curable resin, low-refractive-index particles, and nanodiamond particles;
- and
- a hard coat layer positioned between the substrate and the anti-reflection layer;
- and
- wherein a mass ratio of the low-refractive-index particles and the nanodiamond particles in the anti-reflection layer is in a range from 99:1 to 84:16;
- wherein a content ratio of the low-refractive-index particles in the anti-reflection layer is from 30 mass % to 90 mass %;
- wherein a content ratio of the nanodiamond particles in the anti-reflection layer is from 0.5 mass % to 15 mass %;
- wherein a haze of the anti-reflection film is 0.8% or less, and
- wherein a luminous reflectance of the anti-reflection layer side is in a range from 0.5 to 1.3% when the anti-reflection film consists of the substrate, the anti-reflection layer, and the hard coat layer located between the base material and the anti-reflection layer.
