摘要:
The present invention provides an antiglare film which has (1) appropriate antiglare properties in a frontal direction, (2) no white-blurring (3) no surface appearance such as a kind of orange on the surface of an antiglare layer's side. It is a feature of the antiglare film of the present invention that it has an antiglare layer on a transparent substrate and the antiglare layer includes a binder matrix and particles of an acrylate-styrene copolymer. In addition, the binder matrix includes an acrylic material having a hydroxyl group, a quotient (RA/H) obtained by dividing the average diameter of the particle (RA) by the average thickness of the antiglare layer (H) is in the range of 0.30-0.80, and a product ((nA−nM)×wA/wM) obtained by multiplying a difference between the refractive index of the particles (nA) and the average refractive index of the binder matrix (nM) by a quotient dividing the content of the particles in the antiglare layer (wA) by the content of the binder matrix in the antiglare layer (wM) is in the range of 0.0015-0.003.
