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 untransferable release layer comprises at least a cross-linking resin having a chemical structure comprises at least a side chain A and a side chain B on a principle chain formed of a carbon chain, and cross-linking at least a part of the side chain A and the side chain B. Therefore, the adhesive strength between the substrate and the untransferable release layer can always be stronger than the adhesive strength between the untransferable release layer and the thermally transferable protect layer.
