TRANSFER ELEMENTS AND PROCESS Abstract Pressure-sensitive transfer elements having a polyole- fin 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 C10 to C30 fatty acid, such as zinc stearate, which gels the fatty acid oil, and a quantity of coloring matter. The oil plasti- cizer 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 excel- lent 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,
