Transfer Ribbons and Process for Producing Same Abstract Pressure-sensitive transfer ribbons of the squeeze- out or reusable type having a thin, flexible plastic film foundation having bonded thereto a microporous resinous ink layer containing pressure-exudable liquid ink and designed for use in high speed printing or impact machines in which the ribbon is moving during impact. The invention comprises the formation of a thin friction-reducing or slip-permitting layer of silicone polymer on the rear or impact surface of the film foundation in order to reduce the friction between the moving printing element and the moving film foundation and prevent grabbing of the film foundation and breakdown of the bond between the film foundation and the ink layer.
