Abstract
A method for the metallizing of a luminescent screen comprises the following steps: PA0 the depositing of at least one luminophor coat, comprising at least one binder, on the inner face of the screen; PA0 the depositing of a sub-layer, consisting of at least one aqueous emulsion of a water-insoluble film-forming resin; PA0 the drying of the sub-layer and the heating of this screen to a temperature greater than the minimum temperature for the formation of the film; PA0 the depositing of a finishing layer; PA0 the drying of the finishing layer; PA0 the depositing of a metallic coating on the finishing layer, and, PA0 the volatilizing of the binders of the luminiphor screen, the sub-layer and the finishing layer, wherein the sub-layer and the finishing layer are made from the same aqueous emulsions of water-insoluble film-forming resins, said emulsions having a film-forming temperature of below 45.degree. C. and giving a continuous, thin, resistant, reflective and hydrophobic film.
