Ultrafine particle film, process for producing the same, transparent plate and image display plate
First Claim
1. A transparent plate comprising a transparent substrate, an antistatic layer comprising electrically conductive ultrafine particles formed on said substrate, an anti-reflective layer comprising visible light anti-reflection ultrafine particles arranged in a single layer on said antistatic layer of electrically conductive ultrafine particles and having a surface exhibiting consistent unevenness with a depth of 20-100 nm, and a monomolecular layer of a water repellant agent formed on said anti-reflective layer of visible light anti-reflection ultrafine particles.

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 SnO2 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.
