| 发明名称 | Plastic lens and production method therefor | ||
| 摘要 | To provide a plastic lens having a λ/4 layer exhibiting excellent adhesion between a plastic substrate and a hard coat layer, and a method for producing thereof. A plastic lens containing: a plastic substrate (A); a λ/4 layer (B) that is formed on the plastic substrate, is formed by curing a composition comprising a bifunctional or higher functional acrylate compound, a dendritic aliphatic compound having an acrylate group at an end thereof, and metal oxide particles, and has a thickness of from 50 to 100 nm; and a hard coat layer (C) that is formed on the λ/4 layer directly or through another layer. | ||
