Abstract
A thermal transfer printing system comprising a dye transfer sheet having a dye carrier layer containing at least one sublimable dye and a dye acceptor sheet having a dye-receiving layer with good affinity for the sublimable dye. The two sheets are arranged during printing operations in such a way that they are facing through a slippage means which is in the form of a layer or particles of lubricating or thermally releasable materials. This system is adapted for a printing process in which a relative speed of the dye transfer sheet to a thermal printing head is smaller than a relative speed of the dye acceptor sheet under which the dye transfer sheet is heated in an imagewise pattern to permit the sublimable dye to deposit on the dye-receiving layer according to the imagewise pattern. The dye transfer sheet and the dye acceptor sheet most suitable for use in the system are also described.
