Abstract: Process for producing antireflection layer on viewing screens. A film-like layer of a varnish containing first agent is put on the outer side of the screen and while this layer is still wet it is processed with a second agent in the form of a dispersion in water of a silicate or a silicic acid, the second agent being such as to take part in a reaction with the first agent while it is on the screen. It is furthermore possible for the two agents to be mixed and then put on. Whichever of the two possible forms of the method is used, one may be certain of producing a cured or hardened layer greatly cutting down reflection.
