Abstract

Official abstract text for this publication.

An aspect of the present invention relates to a polarizing lens, which comprises a polarizing layer comprising a dichroic dye and a functional film in this order on a lens substrate, and further comprises a waterborne resin layer between the polarizing layer and the functional film as a layer adjacent to both the polarizing layer and functional film, wherein the waterborne resin layer is greater than 0.50 μm in thickness and has been formed by coating and drying a waterborne resin composition comprising a polyether polyurethane resin and a water-based solvent.

First claim

Opening claim text (preview).

What is claimed is: 1. A polarizing lens, which comprises: a polarizing layer comprising a dichroic dye and a functional film in this order on a lens substrate, and further comprises a waterborne resin layer between the polarizing layer and the functional film as a layer adjacent to both the polarizing layer and functional film, wherein the waterborne resin layer is greater than 0.50 μm and equal to or less than 2.0 μm in thickness and has been formed by coating and drying a waterborne resin composition comprising a polyether polyurethane resin and a water-based solvent. 2. The polarizing lens according to claim 1 , wherein the functional film is a cured film formed by subjecting a curable composition to a curing treatment. 3. The polarizing lens according to claim 2 , wherein the curable composition is a photocurable composition or a heat-curable composition.
