Abstract
The present invention discloses an optical laminate in which the occurrence of interface reflection and interference fringes at the interface of a light transparent base material and a hardcoat layer has been effectively prevented. The optical laminate comprises: a light transparent base material; and a hardcoat layer provided on the light transparent base material, wherein the hardcoat layer is formed of a composition comprising (1) a resin having a weight average molecular weight of not less than 200 and not more than 10000 and containing more than 2 functional groups, (2) a resin having a weight average molecular weight of not less than 200 and not more than 1000 and containing two or less functional groups, and a penetrative solvent.
