Abstract
Abstract In a thermal transfer recording medium having (i) a support, (ii) a heat-fusible layer containing a heat-fusible substance and (iii) a thermoplastic layer containing a thermoplastic polymer, at least one of said layers containing a colorant, the improvement wherein at least one of said heat-fusible layer and said thermoplastic layer contains a fluorine type surfactant. According to the invention, a thermal transfer recording medium having uniform smooth surface by coating, and yet affording printing of high quality on both smooth paper and rough paper can be obtained.
