Title:
SPECTACLE PLASTIC LENS
Document Type and Number:
Japanese Patent JPH1130704
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent the coloration of metal oxides in a hard film and to increase the adhesive strength between the interface of the hard film and a reflection preventive film when the reflection preventive film is formed by sputtering on the spectacle plastic lens having the hard film containing colloidal metal oxides and organic silicon compounds. SOLUTION: On the surface of a high-refractive-index plastic base material 11 containing the colloidal metal oxides and organic silicon compounds, the reflection preventive film 13 in multi-layered structure consisting of a high- refractive-index film and a low-refractive-index film is formed by sputtering, and TiO2 , i.e., titanium oxides are used for the high-refractive-index film 13 of the 1st layer of the reflection preventive film.
