摘要:
A method for the metallization of a luminescent screen comprises the following steps:the depositing, in a known way, of a layer of at least one luminophor containing, among others, a binder on a transparent face panel;the depositing, on said layer, of a sub-layer consisting of an aqueous emulsion of a water-insoluble resin, the emulsion being neutral or alkaline and being capable of forming a hydrophobic film;the drying of the sub-layer;the depositing, on said sub-layer, of a coating consisting of an aqueous emulsion of a water-insoluble film-forming resin, said emulsion containing 0.1% to 4.0% by weight of hydrogen peroxide, 0.25% to 2.5% by weight of a water-soluble polymer and 0.1% to 1.0% by weight of colloidal silica,the drying of the coating;the depositing of a metallic layer, andthe volatilizing of the binder, the sub-layer and the coating.
