Title:
PLASTIC OPTICAL PRODUCT, PLASTIC SPECTACLE LENS AND SPECTACLES
Document Type and Number:
Japanese Patent JP2019015764
Kind Code:
A
Abstract:
To provide a plastic optical product and the like having desired properties such as an antireflection property and excellent adhesiveness and resistance to an external stress.SOLUTION: The plastic optical product includes an optical multilayer film formed directly, or via an intermediate film, on one surface or both surfaces of a plastic base material. The optical multilayer film comprises a tensile stress high refractive index layer made of a high refractive index material having a tensile stress as an internal stress, and a low refractive index layer made of a low refractive index material, and the tensile stress high refractive index layer having a physical film thickness of 10 nm or less is disposed as the first layer of the optical multilayer film, counted from the base material side.SELECTED DRAWING: Figure 1
