PLASTIC LENS AND MANUFACTURING METHOD OF PLASTIC LENS

摘要

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 R1SiX13. The antireflection film contains a coating composition containing at least: an organosilicon compound represented by a general formula of XmR23-mSi-Y-SiR23-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.
