Abstract
A roll-type heat transfer image-receiving sheet comprising a wind-up cylinder and a heat transfer image-receiving sheet which comprises at least a substrate and a coloring material-receiving layer provided thereon, the heat transfer image-receiving sheet being wound around the wind-up cylinder, wherein the maximum surface roughness of the wind-up cylinder in the longitudinal direction thereof is controlled to 40 micrometers or less; the wind-up cylinder is prepared by using pulp as a main component, and a cushioning material is provided between the wind-up cylinder and the heat transfer image-receiving sheet; a lead sheet is provided to the leading end of the heat transfer image-receiving sheet so that the image-receiving sheet can be easily led through a printer; and the heat transfer image-receiving sheet is wound around the wind-up cylinder with the coloring material-receiving sheet outside so that curl will not remain in the image-receiving sheet and that curl will not be developed during a printing process. An image free frost unevenness of density and voids can be produced on the image-receiving sheet without being affected by the roughness or difference in level present on t…
