<p>The thermal transfer sheet (1) has a substrate film (2), and plural kinds of transferable layers, i.e., sublimation dye layers of Yellow (3Y), Magenta (3M), Cyan (3C) and Black (3B) are formed on a front surface of the substrate film (2) side by side in this order. Furthermore, a primer layer (4), a heat resistant layer (5) and a slip layer (6) are formed on a back surface of the substrate film (2) in this order from a position close to the back surface. The heat resistant layer contains a binder resin having a molecular structure, one end portion of which is an end group selected from the group consisting of hydroxyl, amino, carboxyl and mercapto. The slip layer contains silylisocyanate represented by the following formula (1) Rn - Si - (NCO)4-n Äin the formula (1), R denotes alkyl, aryl or vinyl; and "n" denotes an integer of 0 to 3Ü. The slip layer is hardened by reacting an isocyanate group of the silylisocyanate contained therein with the end group of the binder resin contained in the heat resistant layer. <IMAGE></p> |
