Abstract
Pressure-sensitive transfer elements having a plastic film foundation carrying a frangible, complete-release pressure-transfer layer applied by means of a volatile coating vehicle and comprising a solid solution of a fluorescing dye in the resinous binder material of said layer. Such transfer elements are adapted to transfer solid images to the surface of a copy sheet, which images fluoresce under exposure to ultraviolet light and are automatically detectible when sensed on the imaged surface of the copy sheet but are not detectible when sensed through the obverse side of the copy sheet.
