PURPOSE:To enhance the running property and the image density and sensitivity in printing and to enable detection mark to be freely applied, by releasably providing a substrate sheet on the surface of a transparent base material on the other side of a transparent accepting layer through an adhesive layer. CONSTITUTION:A substrate sheet 5, serving as a substrate of a sheet to be heat transferred 1, is releasably provided on the surface of a transfer base material 2 on the other side of a transparent accepting layer 3 and released after an image is formed on the sheet to be heat transferred 1 by heat transfer and before projection is performed by a overhead projector etc. As the substrate sheet 5, a material either transparent or opaque, such as a synthetic paper, a cellulosic fiber paper, and a synthetic resin sheet having a finely irregular surface is used. Provision of the substrate sheet can reduce the thickness of the transparent base material itself, thus enabling reduction of the rigidity of the base material and enhancement of the image density and sensitivity. Additionally, if being marked on the substrate sheet, a detection mark for thermal recorder can be peeled prior to projection. |
