Abstract
Abstract Disclosed is an image receiving sheet for thermal transfer recording comprising: a support and an image receiving layer thereon, wherein the image receiving layer comprises an outermost layer being farthest from the support and a layer other than the outermost layer, and a glass transition temperature of a first binder used in the outermost layer is higher than that of a second binder used in the layer adjacent to the outermost layer.
