ABSTRACT:
The material comprises a base carrier coated with at least one layer of a thermofusible ink which has a melting temperature within the range from 50.degree. to 90.degree. C. and comprises at least one coloring substance and a thermofusible vehicle for this coloring substance, characterized in that the ink comprises from 15 to 50%, relative to the weight of the ink, of at least one heat transfer polymer resin mixed homogeneously with the other constituents of the ink, having a softening point of between 60.degree. and 113.degree. C., a tensile strength lower than 8 N/mm.sup.2 at 20.degree. C., an elongation of between 0.04 and 6 mm, a melt viscosity lower than 5 Pas at 200.degree. C., and an adhesiveness to the base carrier such that, at the heat transfer temperature, the force needed to separate the ink from the said carrier is greater than the force needed to break the internal cohesion of the ink.
