The invention discloses a
thermal transfer ribbon which comprises an ink layer, a
release agent layer, base material and a thermal resistant layer. The ink layer comprises water-dilutable resin, inorganic nanoscale
pigment, organic
pigment, dispersant, curing agent, deformer and deionized water. The
release agent layer comprises organic
silicone resin, water-based
wax emulsion, talcum
powder and deionized water. The base material includes
polyester film and thermal-conductive
silicone grease. The thermal resistant layer comprises perfluorocarbon, organic
silicone resin and deionized water. The invention further discloses a preparation method for the
thermal transfer ribbon. The preparation method includes steps of stirring, mixing,
drying and the like. The thermal-conductive
silicone grease is added to the base material
polyester film, using temperature of the
thermal transfer ribbon is increased,
thermal resistance and adaptability of the thermal transfer ribbon are improved, and printing speed is increased. The thermal resistant layer is added to the thermal transfer ribbon, and accordingly performance of the thermal transfer ribbon is improved. The release layer is added, and accordingly the ink is easier to separate from the base, strippable level is high, printing effect is better, and writing is clearer. The deionized water is used as
solvent, and accordingly production cost is reduced, and
cost performance of the thermal transfer ribbon is better.
