Abstract
A coated transfer sheet comprising a substrate having a first and second surface; optionally at least one barrier layer overlaying said first surface, at least one release layer overlaying said at least one barrier layer or, when the barrier layer is not present, said first surface of the substrate; and an optional image receiving layer comprising an ethylene acrylic acid co-polymer dispersion; wherein the coated transfer sheet exhibits cold peel and hot peel properties when transferred, and may be used in electrostatic printers and copiers or other devices in which toner particles are imagewise applied to a substrate. The addition of elastomeric polymers and polyurethanes help provide enhanced wash stability and chemical stability.
