Abstract

An aspect of the present invention relates to a method of manufacturing an eyeglass lens, which comprises forming a functional film by coating a coating liquid by spin coating on a lens substrate, wherein the coating liquid is a curable composition comprising a curable component selected from the group consisting of an organic silicon compound and an acrylate compound, and an essential solvent in the form of a ketone or ether solvent with a relative evaporation rate of less than 1.00 when denoting an evaporation rate of butyl acetate as 1.00.

Claims

1. A method of manufacturing an eyeglass lens, which comprises:

forming a functional film by coating a coating liquid by spin coating on a lens substrate, wherein

the coating liquid is a curable composition comprising a curable component selected from the group consisting of an organic silicon compound and an acrylate compound, and an essential solvent in the form of a ketone or ether solvent with a relative evaporation rate of less than 1.00 when denoting an evaporation rate of butyl acetate as 1.00.

2. The method of manufacturing an eyeglass lens according to claim 1, wherein a boiling point of the essential solvent is equal to or higher than 115°

C. and equal to or lower than 170°

C.

3. The method of manufacturing an eyeglass lens according to claim 1, wherein the essential solvent is selected from the group consisting of diacetone alcohol, propylene glycol monomethyl ether acetate, propylene glycol monomethyl ether, and ethylene glycol monoethyl ether acetate.

4. The method of manufacturing an eyeglass lens according to claim 1, wherein a polarizing layer comprising a dichroic dye is formed on the lens substrate and the functional film is formed directly, or indirectly through another layer, on the polarizing layer.

5. The method of manufacturing an eyeglass lens according to claim 4, which comprises forming, as the another layer, a primer layer that enhances adhesion between the polarizing layer and the functional film.
