Abstract
Abstract A printable sheet having a high printing quality and a high handling resistance. At least one of the sides of the sheet is treated with a composition which comprises at least one filler and at least one elastomeric binder. The elastomeric binder is selected from the group consisting of aqueous dispersions of polyurethane, acrylate copolymers, optionally carboxylated styrene-butadiene copolymers, and polymers of which one of the monomers is acrylonitrile, isoprene, or neoprene, or mixtures thereof. The sheet can be used for manufacturing protected documents.
