Abstract
The invention describes novel coating agents that include a polymer, one or more latent reactive groups and one or more noncovalent linking groups, the noncovalent linking groups selected to interact with a substrate to which the coating agent is applied.
Claims20
A method for forming a coated article, the method comprising steps of (a) applying a base coating composition to a surface of the article, the base coating composition comprising a polymer that includes a polymaleic acid derivative or a copolymer of a polymaleic acid derivative, one or more photoreactive groups that are pendent from the polymer, and one or more siloxane groups;
- and (b) exposing the base coating composition to actinic energy, thereby activating at least some of the photoreactive groups and covalently coupling the base coating composition on the surface.
An article comprising a substrate and a multilayer coating comprising a base coating layer and an overcoat layer, wherein the base coating layer comprises (a) a polymaleic acid derivative or a copolymer thereof, (b) one or more aryl ketones;
- and (c) one or more sihoxane groups having a formula:
- wherein wavy lines represent the polymaleic acid derivative, and wherein the overcoat layer comprises active agent.
An article comprising a substrate and a base coating disposed on a surface of the substrate, the base coating comprising:
- (a) a polymer that includes a polymaleic acid derivative;
- (b) one or more photoreactive groups that are pendent from the polymer;
- and (c) one or more siloxane groups.
