Abstract
A coated transfer sheet comprising a substrate having a first and second surface; at least one thermosetting and/or UV curable polymeric barrier layer overlaying said first surface, at least one release layer overlaying said at least one barrier layer; and an optional image receiving layer; wherein the coated transfer sheet exhibits cold peel, hot peel, or warm peel properties when transferred. The sheet may be imaged in electrostatic printers and copiers or imaged with other image marking techniques such as Ink Jet, conventional printing inks, thermal wax, and all craft-type markers. The resulting image may be imagewise applied to a receptor.
