ABSTRACT:
There is provided a transfer sheet made up of a flexible substrate, a laminated image part composed of metal layer and printed film layer, and an adhesive layer formed on the image part. The printed film layer has an elongation at break greater than approximately 4% and has a thickness greater than approximately 4 .mu.m. The peel strength between the substrate and the metal layer is smaller than approximately 10 g/25 mm width, and the adhesion strength between the metal layer and the printed film layer and between the printed film layer and the adhesive layer is greater than approximately 4 kg/cm.sup.2. Because of these characteristic values, the transfer sheet permits the image part including the metal layer to be released without breakage and permits satisfactory transfer.
