Abstract

L'invention est relative à des produits antistatiques. Le produit, en feuille ou en bande, comprend un support et une couche antistatique. Cette couche est pratiquement amorphe et contient une substance antistatique qui comprend au moins 80 % en masse de pentoxyde de vanadium et, en outre, un oxyde choisi parmi les oxydes des métaux alcalins, des métaux de transition et des terres rares. Application à la préparation de produit photographique comprenant une couche antistatique.The invention relates to antistatic products. The product, in sheet or strip, comprises a backing and an antistatic layer. This layer is practically amorphous and contains an antistatic substance which comprises at least 80% by mass of vanadium pentoxide and, in addition, an oxide selected from the oxides of alkali metals, transition metals and rare earths. Application to the preparation of a photographic product comprising an antistatic layer.
