摘要：
The invention concerns an aqueous composition for an antistatic layer and a film comprising this layer.
The aqueous composition for antistatic layer according to the invention comprises vanadium pentoxide and a polyurethane including no sulfonated groups and stable in an acidic medium, the weight ratio of vanadium pentoxide to polyurethane V 2 O 5 /polyurethane being preferably between 1:200 and 5:1.
Such a composition can be used for transparencies for photocopy, for mounting supports in the field of printing, or in photographic or magnetic products and in packaging.
