ABSTRACT:
Disclosed are an ultrafine particle film which is effective for the prevention of an electrostatic charge and reflection and can be applied to a large area at a low cost, a cathode ray tube to which the ultrafine particle film is applied, and image display plate to which the ultrafine particles is applied, and a process for producing the ultrafine particle film which comprises attaching a coating solution bath to a Braun tube surface and the like, introducing a containing solution containing anti-reflection SiO.sub.2 ultrafine particles and antistatic SnO.sub.2 ultrafine particles, and elevating up or down on the Braun tube surface and the like at a constant rate.
