Abstract
Abstract The present invention relates to a sublimation transfer system color hard-copy printing paper and its object is to present an optimum coloring when the color hard-copying according to the subtractive color mixing process is carried out. To this end, the sublimation transfer system color hard-copy printing paper according to the present invention is provided at least on its surface with a resin layer containing a metal compound selected from Al, Mg, Ca and Sn wherein the sublimation dye is transferred and then colored on this resin layer.
