Abstract
An antireflective coating may be formed on visible light transmitting materials. The antireflective coating may a stack of two coating layers. The first coating layer may be formed from a composition that includes a metal alkoxide. The first coating layer may be cured by the application of ultraviolet light or heat. The second coating layer may be formed from a second composition that includes an initiator and an ethylenically substituted monomer. The second composition may be cured by the application of ultraviolet light. The antireflective coatings may be applied to a plastic lens or a plastic lens mold.
Claims152
A method for forming an at least partially antireflective coating on a visible light-transmitting substrate, comprising:
- applying a first composition to at least one surface of the visible light-transmitting substrate to form a first coating layer, the first composition comprising a first metal alkoxide;
- applying a second composition to the first coating layer, the second composition comprising, an ethylenically substituted monomer and a second metal alkoxide, wherein the second composition is curable by the application of ultraviolet light;
- and
- directing ultraviolet light toward the second composition, wherein the ultraviolet light initiates curing of the second composition to form a second coating layer.
A plastic eyeglass lens comprising an at least partially antireflective coating, formed by the method, comprising:
- applying a first composition to at least one surface of a non-coated plastic eyeglass lens to form a first coating layer, the first composition comprising a first metal alkoxide;
- applying a second composition to the first coating layer, the second composition comprising an ethylenically substituted monomer and a second metal alkoxide, wherein the second composition is curable by the application of ultraviolet light;
- and
- directing ultraviolet light toward the second composition, wherein the ultraviolet light initiates curing of the second composition to form a second coating layer.
A method for forming an at least partially antireflective coating on a lens, comprising:
- applying a first composition to at least one surface of the lens to form a first coating layer, the first composition comprising a first metal alkoxide;
- applying a silicon containing composition to the first composition to form a silicon layer, the silicon containing composition comprising colloidal silicon or a silane monomer;
- applying a second composition to the silicon layer, the second composition comprising an an ethylenically substituted monomer and a second metal alkoxide, wherein the second composition is curable by the application of ultraviolet light;
- and
- directing ultraviolet light toward the second composition, wherein the ultraviolet light initiates curing of the second composition to form a second coating layer.
A plastic eyeglass lens comprising an at least partially antireflective coating, formed by the method, comprising:
- applying a first composition to at least one surface of a non-coated plastic eyeglass lens to form a first coating layer, the first composition comprising a first metal alkoxide;
- applying a silicon containing composition to the first composition to form a silicon layer, the silicon containing composition comprising colloidal silicon or a silane monomer;
- applying a second composition to the first coating layer, the second composition comprising an ethylenically substituted monomer and a second metal alkoxide, wherein the second composition is curable by the application of ultraviolet light;
- and
- directing ultraviolet light toward the second composition, wherein the ultraviolet light initiates curing of the second composition to form a second coating layer.
