Abstract:
A thermal transfer film comprising a coloring layer formed on a substrate film via an intermediate layer,wherein the intermediate layer is not transferable from the substrate and contains a thermally fusible substance and a non-transferable binder resin, the melt viscosity of the thermally fusible substance in the temperature range 15 to 25Â° C. higher than the fuse peak temperature defined in JIS K7121-1987 of the thermally fusible substance is 100 mPa's or more and 1000 mPa's or less, the fuse peak temperature defined in JIS K7121-1987 of the thermally fusible substance is in the range of 50 to 110Â° C., and the crystallization peak temperature defined in JIS K7121-1987 of the thermally fusible substance is in the range of âˆ’20 to 100Â° C., and the crystallization peak temperature of the thermally fusible substance is lower than the fuse peak temperature by 10Â° C. or more, and the softening temperature of the binder resin measured by the ring and ball method defined in the JIS K2207-1980 is 130Â° C. or more and 400Â° C. or less.
