摘要： There is provided a thermal transfer image-receiving sheet which has dyeability high enough to realize high-speed printing and low-energy printing, permits a protective layer to be thermally transferred onto an image formed on the thermal transfer image-receiving sheet, is free from heat fusing to a thermal transfer sheet at the time of image formation on the thermal transfer image-receiving sheet, and has satisfactory separability from the thermal transfer sheet. The thermal transfer image-receiving sheet comprises: a substrate sheet; and a receptive layer provided on at least one side of the substrate sheet, said receptive layer comprising at least a combination of a cellulose ester resin (A) having a degree of acetylation of 10 to 30% with a cellulose ester resin (B) having a degree of acetylation of less than 6%, the total degree of acetylation of the cellulose ester resin (A) and the cellulose ester resin (B) being 8 to 14%, the content of hydroxyl groups in the cellulose ester resin (A) and the content of hydroxyl groups in the cellulose ester resin (B) each being not more than 6% by weight, the remaining hydroxyl groups having been esterified with an organic acid excluding acetic acid. By virtue of the above construction, the thermal transfer image-receiving sheet can realize printing of an image thereon with high dyeability at a high speed, has excellent separability from a thermal transfer sheet, is free from smudge and blurring derived from plasticizers, and permits a protective layer to be adhered onto the receptive layer.

摘要： A protective layer transfer sheet is provided that can form by transfer a protective layer which possesses high weathering resistance and, when formed onto an image, can prevent a dye in the image from being transferred or fused to a vinyl chloride case, can prevent the dye constituting the image being faded upon exposure to light, can additionally impart good fastness to water, alcohols and the like, and thus can impart excellent fastness properties to a print. A print produced by using the protective layer transfer sheet is also provided. The protective layer transfer sheet comprises: a substrate sheet; and a thermally transferable protective layer provided on at least a part of one side of the substrate sheet, the protective layer being formed of a laminate having a multilayer structure comprising at least a layer composed mainly of an acrylic resin and a layer composed mainly of a polyester resin provided in that order on the substrate sheet.
