A glass sheet covered with a colored film, which is produced by forming a transparent or translucent colored film containing fine gold particles with a mean diameter of 10 nm or less dispersed therein on te whole or part of the surface of the sheet. The colored film is formed by applying to the sheet surface a paste containing a composite material comprising a polymeric material and fine gold particles dispersed therein and preferably containing also a gold-particle growth inhibitor and heating the sheet thus treated, whereby the colored film is fired on the sheet surface.
La présente invention concerne une feuille de verre recouverte d'un film coloré, produite en formant, sur tout ou partie de la surface de la feuille, un film coloré transparent ou translucide contenant de fines particules d'or, d'un diamètre moyen inférieur ou égal à 10 nm, dispersées dedans. Le film coloré est formé en appliquant sur la surface de la feuille une pâte contenant une matière composite faite d'un polymère et de fines particules d'or qui y sont dispersées, et contenant aussi, de préférence, un inhibiteur de croissance des particules d'or. On chauffe la feuille ainsi traitée, ce qui a pour effet de cuire le film coloré à la surface de cette feuille.
