ABSTRACT:
An anti-reflection coating with n layers on an optical part substrate made of synthetic resin wherein n is 3, 4, or 5, and the first layer at the air side comprises silicon dioxide (SiO.sub.2), and the n-th layer on the surface of the synthetic resin comprises ceric oxide (CeO.sub.2) is excellent in reflection reducing effect and does not result in the age-based change of the refractive index. And that the very good adhesion of the reflection reducing coating with the substrate results in hardness of layer stripping.
Further an anti-reflection coating of the invention has reflection reducing effect in the near-infrared region.
