An antistatic composition for treating a substrate such as paper for use in a photocopier or the like, in rolls, or bundles in which sheets of the substrate are individually fed from a bundle of sheets of the substrate, comprises a single phase hydrocarbon oil composition. The hydrocarbon oil may optionally include additional antistatic additives. The composition reduces static between the individual sheets in the bundle, thus reducing paper misfeeds and jams when individual sheets in the bundle are fed into the photocopier. Also disclosed is a method of treating a substrate for use in a photocopier in which sheets of the substrate are individually fed from a bundle of sheets of the substrate, or rolls of a substrate, with an antistatic composition to reduce static between the individual sheets of the substrate. The method includes applying an antistatic composition including a hydrocarbon oil to at least one lateral margin of the bundle of sheets of the substrate.

L'invention concerne une composition antistatique pour le traitement d'un substrat du type papier destiné à être utilisé dans une photocopieuse ou autre, sous forme de rouleaux ou de liasses de substrat, les feuilles étant alimentées individuellement. Ladite composition est à base d'huile hydrocarbonée à phase unique. La composition a pour effet de réduire les phénomènes statiques entre les différentes feuilles d'une liasse, ce qui réduit les risques de défaut ou de bourrage d'alimentation papier lorsque les feuilles sont alimentées individuellement dans une photocopieuse. L'invention concerne également un procédé de traitement de substrat pour photocopieuse, les feuilles d'une liasse ou d'un rouleau de substrat étant alimentées individuellement. On applique ainsi au moins à une marge latérale de la liasse ou du rouleau une composition antistatique visant à réduire les phénomènes statiques entre les différentes feuilles de substrat.
