Patent ID: 7990617

Claim:
An optical laminate comprising 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 has a refractive index of not more than 1.5, the low-refractive index layer contains a contamination preventive agent and/or a slipperiness imparting agent, and the contamination preventive agent and/or slipperiness imparting agent as additives are added so that the concentrations of the contamination preventive agent and/or slipperiness imparting agent are increased from the surface of the hard coat layer toward the surface of the low-refractive index layer, wherein the contamination preventive agent and/or slipperiness imparting agent is a fluorocompound represented by general formula: (A) w -(B) x -(D) y -CF 3 wherein A represents one or at least two groups selected from the group consisting of CF 2 , CFCF 2 , and C(CF 2 ) 2 ; B represents one or at least two groups selected from the group consisting of OCF 2 CF 2 , OCF 2 CF(CF 2 ), OCF 2 C(CF 2 ) 2 , OCF(CF 2 CF(CF 2 ), OCF(CF 2 )C(CF 2 ) 2 , OC(CF 2 ) 2 CF(CF 2 ), and OC(CF 2 ) 2 C(CF 2 ) 2 ; D represents one or at least two groups selected from the group consisting of OCH 2 CH 2 , OCH 2 CH 2 CH 2 , and OC(O)(CH 2 )z; and w, x, y, and z are a number of more than 0 and not more than 50.
