ABSTRACT:
A protect layer transfer sheet of the present invention comprises a substrate, an untransferable release layer and a thermally transferable protect layer, the protect layer being disposed on at least one area of a surface of the substrate by the medium of the release layer. The release layer contains at least one substance selected from the group consisting of inorganic particles having a mean particle size of 40 nm or less, alkyl vinyl ether--maleic anhydride copolymer, derivatives of the alkyl vinyl ether--maleic anhydride copolymer and ionomer. According to the present invention, it is possible that a protect layer is surely and constantly transferred on an image formed in a printed product at all times. Furthermore it is also possible to make the thermally transferable protect layer a single-ply structure by omitting an adhesive layer. The single-ply structure of the protect layer has an improved transparency, thus increasing the highest density of a highly quality image covered with the protect layer.
