Paint for inhibiting rust staining
 External rust-staining, for example at the exterior of buildings or on the superstructure or topside of ships, caused by rust dripping onto a surface is inhibited by painting the surface with a top-coat paint comprising a film-forming binder and a substance capable of reacting with rust to form a colorless material. The said substance can for example be a polyphosphonate salt pigment, an oxalate or a glass releasing phosphate ions.
