Abstract
An ultrafine particle film which has excellent anti-staining properties, is effective for the prevention of electrostatic charge and reflection of visible light and can be applied to a large area at low cost, and an image display plate such as the one adapted to a Braun tube to which the ultrafine particle film is applied, and a process for producing the ultrafine particle film which comprises attaching a coating solution bath 22 to a surface of a Braun tube 21, filling the bath with a coating solution 23 containing antistatic SnO.sub.2 ultrafine particles so that the surface of the Braun tube 21 is covered with the coating solution, exposing the coated Braun tube surface at a predetermined rate to form an electrically conductive film on the Braun tube surface, the above process being repeated by using a coating solution containing the visible light anti-reflection ultrafine particles to form a visible light anti-reflection film on the electrically conductive film, and further applying thereon a water repellency treatment.
