Patent ID: 7981506

Claim:
A plastic lens comprising a plastic lens substrate and a hard coat layer on the plastic lens substrate, and an organic antireflection film on the hard coat layer, the plastic lens substrate including at least a sulfur atom, wherein the plastic lens substrate comprises a thiourethane based resin and/or an episulfide based resin, and wherein the plastic lens substrate is tinted, the hard coat layer being a coating film formed with a coating composition which includes at least the following Component A and Component B, the organic antireflection film being a coating film which includes at least the following Component C and Component D, and has a refractive index that is lower than the refractive index of the hard coat layer by 0.10 or more, and the plastic lens including a primer layer between the plastic lens substrate and the hard coat layer: Component A: metal oxide fine particles including titanium oxide having a rutile crystal structure, wherein the titanium oxide is a composite oxide with tin oxide and silicon dioxide, Component B: an organic silicon compound represented by the general formula: R 1 SiX 1 3 (wherein, R 1 represents an organic group having a polymerizable reactive group and having two or more carbon atoms; and X 1 represents a hydrolytic group), Component C: an organic silicon compound represented by the general formula: R 2 n R 3 m SiX 2 4-n-m (wherein, R 2 represents an organic group having a polymerizable reactive group; R 3 represents a hydrocarbon group having 1 to 6 carbon atoms; X 2 represents a hydrolytic group; n represents 0 or 1; and m represents 0 or 1; and where n or m cannot be 0 at the same time), and Component D: silica fine particles having a mean particle diameter of 1 to 150 nm and having voids inside thereof; wherein the primer layer is a coating film formed with a coating composition including the following Component E and Component F: Component E: an organic resin polymer having a polar group, and Component F: metal oxide fine particles including titanium oxide, wherein the titanium oxide is a composite oxide with tin oxide and silicon dioxide.
