    • A thermal transfer film comprises a coloring layer formed on a substrate film via an intermediate layer, wherein the intermediate layer 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 25° C. higher than the fuse peak temperature of the thermally fusible substance is in the range of 100 to 1000 mPa·s, the fuse peak temperature of the thermally fusible substance is in the range of 50 to 110° C., the crystallization peak temperature of the thermally fusible substance is in the range of −20 to 100 ° C., the crystallization peak temperature of the thermally fusible substance is lower than the fuse peak temperature by 10° C. or more, and the softening temperature of the binder resin measured by the ring and ball method is in the range of 130 to 400° C. This thermal transfer film is capable of forming a printed product with a good printing quality.
    • 热转印膜包括通过中间层在基材膜上形成的着色层,其中中间层含有热熔性物质和不可转移的粘合剂树脂,热熔性物质的熔体粘度在15〜25℃的范围内 高于热熔物质的熔丝峰值温度在100〜1000mPa·s的范围内,则热熔物质的熔断峰温度在50〜110℃的范围内,结晶峰 热熔性物质的温度在-20〜100℃的范围内,热熔性物质的结晶峰值温度比熔丝峰值温度低10℃以上,粘合剂的软化温度 通过环球法测定的树脂在130〜400℃的范围内。该热转印膜能够形成印刷品质良好的印刷品。
