Abstract:
The present invention discloses an optical laminate comprising a light-transparent base material and a low-refractive index layer provided on the light-transparent base material, the low-refractive index layer simultaneously having both contamination preventive properties and slipperiness. The optical laminate comprises a light-transparent base material, and a hard coat layer and a low-refractive index layer provided in that order on the light-transparent base material, wherein the low-refractive index layer contains a contamination preventive agent and/or a slipperiness imparting agent, and contamination preventive agent and/or slipperiness imparting agent are added so that the concentrations of the contamination preventive agent and/or slipperiness imparting agent have a concentration gradient from the surface of the hard coat layer toward the surface of the low-refractive index layer.
