Title:
OPTICAL COMPONENT, LENS UNIT, ANTI-FOGGING AGENT AND METHOD FOR PRODUCING OPTICAL COMPONENT
Document Type and Number:
WIPO Patent Application WO/2019/064772
Kind Code:
A1
Abstract:
This optical component comprises a light-transmitting member and an anti-fogging coating film that is formed on a surface of a light-transmitting member or is formed on a functional coating film formed on said surface. The anti-fogging coating film is formed by applying an anti-fogging agent, which contains a polymer obtained by copolymerizing raw materials including an anchor material and a hydrophilic base material, to the surface or the functional coating film. The hydrophilic base material has a betaine structure. The thickness of the anti-fogging coating film is 0.2-1.5 μm. It is preferable for the anti-fogging coating film to be disposed on the functional coating film, and for the functional coating film to be an anti-reflection coating film.
