Abstract
A sublimation type thermosensitive image transfer recording medium which can be used in repetition, comprising a support; a dye supplying layer formed on the support, comprising a sublimable dye and at least one binder agent in which the sublimable dye is dissolved or dispersed; and an image transfer facilitating layer formed on the dye supplying layer, comprising the sublimable dye and at least one organic binder agent in which the sublimable dye is dissolved or dispersed, the dye supplying layer and the image transfer facilitating layer being structured in such a manner that when the dye supplying layer and the image transfer facilitating layer are separately formed on a substrate, and the layers are separately superimposed on the same receiving sheet, with application of an equal quantity of thermal energy thereto, the amount (weight/unit time.unit area) of the sublimable dye transferred from the dye supplying layer to the receiving sheet is greater than the amount (weight/unit time.unit area) of the sublimable dye transferred from the image transfer facilitating layer to the receiving sheet.
