Abstract
A protective layer transfer sheet comprising a thermally transferable protective layer releasably provided on a substrate sheet is provided which, when a protective layer is formed by thermal transfer onto an image-receiving sheet with an image formed thereon, can prevent carrying troubles, such as meandering or cockling, within a printer. In a protective layer transfer sheetcomprising a substrate sheet, a heat-resistant slip layerprovided on one side of the substrate sheet, and a thermally transferable protective layerreleasably provided on at least a part of the surface of the substrate sheetremote from the heat-resistant slip layer, bringing the coefficient of friction between the surface of the protective layer and the surface of the image-receiving sheet before thermal transfer to 0.05 to 0.5 in terms of μ(coefficient of static friction) and μ (coefficient of dynamic friction) with the value of μ/μ being 1.0 to 1.5, that is, bringing the coefficient of static friction and the coefficient of dynamic friction to the above respective ranges and reducing the difference between the coefficient of static friction and the coefficient of dynamic friction to the above range, can prevent carrying troubles, such as meandering or cockling, within a printer.
