ABSTRACT:
Flexible digital optical media, such as optical tapes, are provided with an aqueous-applied backing layer which provides excellent performance with regard to runnability, scratch resistance, abrasion resistance, frictional properties and curl characteristics. The backing layer comprises a film-forming water-dispersible polymeric binder and water-dispersible static-dissipative filler particles and a water-dispersible lubricant is either incorporated within the backing layer or forms a thin film over the surface of the backing layer.
