Anti-fingerprint coatings

A method of forming an article with a nanostructured surface layer, comprising:

• providing a substrate;
• depositing a film on said substrate;
• decomposing said film to form a decomposed film;
• and
• etching said decomposed film to form a nanostructured layer comprising a plurality of spaced apart nanostructured features comprising a contiguous, protrusive material, wherein said nanostructured features are sufficiently small that said nanostructured layer is optically transparent, applying a continuous layer to a plurality of surfaces of the nanostructured features,
• wherein the continuous layer has a thickness of from 1 to 60 nm, and
• wherein the continuous layer renders the plurality of surfaces of the nanostructured features both hydrophobic and oleophobic with respect to fingerprint oil comprising eccrine secretions and sebaceous secretions.
