Abstract:

A coating material (10) for coating an article is described. The coating material (10) comprises a surface (100) having an optical interference coating (110) thereon. The coating material (10) improves protection of the article from incident electromagnetic radiation having a predetermined wavelength. The coating material (10) may retroreflect at least some of the incident electromagnetic radiation, for example towards a source (e.g. a laser) thereof. An article having a coating provided by such a coating material and methods of providing such coating materials are also described.
