  • Patent number: 7981506
    Abstract: The plastic lens has the hard coat layer on a plastic lens base material containing at least sulfur atom and the organic anti-reflection film on the hard coat layer and further has a primer layer between the plastic lens base material and the hard coat layer. The hard coat layer comprises metal oxide particulates at least containing titanium oxide with rutile-type crystal structure and an organic silicon compound expressed by general Formula: R1SiX13. The organic anti-reflection film comprises a coating composition at least containing an organic silicon compound expressed by general Formula: R2nR3 mSiX24-n-m and silica system particulates of 1 to 150 nm mean particle diameter and has a refractive index which is lower than that of that of the hard coat layer by 0.10 or more.

  • Publication number: 20090011255
    Abstract: A production method, which is a production method for a product having a stain-proofing layer, containing a step of forming the stain-proofing layer by using a fluorine-containing composition on a surface of an organic anti-reflection layer which is a lower layer of the stain-reflection layer is provided. The fluorine-containing composition includes at least one type of fluorosilane compound selected from the group consisting of fluorosilane compounds each having a molecular weight in the range of from 1000 to 10000 and at least one type of fluorosilane compound selected from the group consisting of fluorosilane compounds each having a molecular weight in the range of from 100 to 700. By these arrangements, the stain-proofing layer having sufficient durability can be formed on the organic anti-reflection layer.
