<p>Process for metallising a luminescent screen comprising the following steps: - deposition, in a known manner, of a layer of at least one luminophore containing inter alia a binder, on a transparent pane (12), - deposition on the said layer of a sub-layer (40) consisting of an aqueous emulsion of a water-insoluble resin, the emulsion being neutral or alkaline and exhibiting an ability to form a water- repellent film, - drying of the sub-layer, - deposition on the said sub-layer of a coating (42) consisting of an aqueous emulsion of a water-insoluble film-forming resin, this 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, - drying of the coating, - deposition of a metal layer (44), and - volatilisation of the binder, of the sub-layer and of the coating. Application to television screens. <IMAGE></p> |
