ABSTRACT:
Pressure-sensitive transfer elements having a polyolefin film foundation carrying a solvent-applied, pressure-transferable complete-release or "correctable" imaging layer comprising a normally-hard resinous binder material, a non-hydroxylated fatty acid oil plasticizer, such as rapeseed oil, which softens or embrittles the resin, a metal salt of a C.sub.10 to C.sub.30 fatty acid, such as zinc stearate, which gels the fatty acid oil, and a quantity of coloring matter. The oil plasticizer of the transfer layer is rendered non-migratory and does not penetrate the polyolefin film foundation, even over an extended period of time, and the transfer layer has excellent cohesive properties and excellent frangibility whereby it transfers readily and completely to a copy paper from the film foundation and yet, according to one embodiment, can be removed completely and cleanly from the copy paper by means of conventional lift-off ribbons or tapes.
