Patent ID: 7854508

Claim:
A plastic lens, comprising: a plastic lens base material; a primer layer formed on the plastic lens base material; a hard coat layer formed on the primer layer; and an organic antireflection film formed on the hard coat layer, wherein the plastic lens base material contains at least a sulfur atom, the hard coat layer is a coating film formed of a coating composition containing at least Component A and Component B below, the organic antireflection film is a coating film formed of a coating composition containing at least Component C, Component D and Component E, a refractive index of the antireflection film being lower than that of the hard coat layer by 0.10 or more, Component A to Component E being as follows: Component A: fine metal oxide particles containing a titanium oxide with a rutile type crystalline structure; Component B: an organosilicon compound represented by a general formula of R 1 SiX 1 3 , wherein R 1 represents an organic group with carbon number of 2 or more and having a polymerizable reactive group; and X 1 represents a hydrolyzable group; Component C: an organosilicon compound represented by a general formula of X m R 2 3−m Si—Y—SiR 2 3−m X m , wherein R 2 represents a monovalent hydrocarbon group with carbon number of 1 to 6; Y represents a divalent organic group containing one or more fluorine atom; X represents a hydrolyzable group; and m represents an integer of 1 to 3; Component D: an epoxy group-containing organic compound containing one or more epoxy group in a molecule, Component D containing at least one type selected from the group consisting of: a compound represented by a general formula of R 3 nR 4 pSiZ 4−[n+p] , wherein R 3 and R 4 each represent an organic group with carbon number of 1 to 16, at least one of R 3 and R 4 containing an epoxy group; Z represents a hydrolyzable group; and n and p each represent an integer of 0 to 2, an equation 1≦n+p≦3 being satisfied; and a compound represented by a general formula (1) below: wherein, R 5 to R 16 each represent an organic group, at least one of R 5 to R 16 containing an epoxy group; and q, r, s and t each represent an integer of 0 to 12; and Component E: fine silica particles with average particle size of 1 to 150 nm.
