Abstract

PROCEDE POUR LA FABRICATION DE LUMINOPHORES REVETUS DE PIGMENTS. CE LUMINOPHORE EST PREPARE 1 EN AJOUTANT A UNE SUSPENSION AQUEUSE D'UN LUMINOPHORE ET D'UN PIGMENT, UNE EMULSION DE POLYMERE ANIONIQUE AYANT UNE TEMPERATURE MINIMUM FILMOGENE INFERIEURE A 30C; 2 EN AJOUTANT ENSUITE UNE EMULSION DE POLYMERE CATIONIQUE AYANT UNE TEMPERATURE MINIMUM FILMOGENE DE 30C OU PLUS BASSE; 3 EN VERSANT UNE EMULSION DE POLYMERE ANIONIQUE AYANT UNE TEMPERATURE FILMOGENE MINIMUM DE 30C OU PLUS ELEVEE, DANS LE MELANGE OBTENU, ET 4 EN RENDANT LE MELANGE FINAL NEUTRE OU FAIBLEMENT ACIDE. CE LUMINOPHORE REVETU DE PIGMENT SE TAMISE A LA FIN BEAUCOUP MIEUX, FORME UNE PELLICULE FLUORESCENTE AYANT D'EXCELLENTES PROPRIETES ET EST UTILISE DANS LES TUBES A RAYONS CATHODIQUES POUR LES RECEPTEURS DE TELEVISION EN COULEURS.
