CA 2623559

A plastic lens includes: a plastic lens base material; a hard coat layer formed on the plastic lens base material; an organic antireflection film formed on the hard coat layer; and a primer layer between the plastic lens base material and the hard coat layer. The plastic lens base material contains at least a sulfur atom. The hard coat layer contains at least: fine metal oxide particles containing a titanium oxide having a rutile-type crystalline structure; and an organosilicon compound represented by a general formula of R1SiX1 3. The antireflection film contains a coating composition containing at least: an organosilicon compound represented by a general formula of XmR2 3- mSi-Y-SiR2 3-mXm; an epoxy group-containing organic compound containing one or more epoxy group in a molecule; and fine silica particles with average particle size of 1 to 150 nm, the antireflection film having a refractive index lower than that of the hard coat layer by 0.10 or more.

Le verre organique, selon l~invention, comprend : une matière de base de verre organique ; une couche de revêtement dur formée sur la matière de base du verre organique ; un film antireflet organique formé sur la couche de revêtement dur ; et une couche primaire entre la matière de base du verre organique et la couche de revêtement dur. La matière de base du verre organique contient au moins un atome de soufre. La couche de revêtement dur contient au moins : de fines particules d'oxyde de métal contenant un oxyde de titane ayant une structure cristalline de type rutile ; et un composé organosilicié représenté par la formule générale R1SiX1 3. Le film antireflet contient une composition de revêtement contenant au moins : un composé organosilicié représenté par la formule générale XmR2 3-mSi-Y-SiR2 3-mXm ; un composé organique avec groupe époxy contenant un ou plusieurs groupes époxy dans une molécule ; et de fines particules de silice ayant une taille moyenne des particules de 1 à 150 nm, le film antireflet ayant un indice de réfraction inférieur de 0,10 ou plus à celui de la couche de revêtement dur.
