The invention discloses a
heat transfer printing
colored tape capable of being used on a band-shaped or card-shaped
label. The
heat transfer printing
colored tape comprises a tape base, one face of the tape base is coated with a
printing ink layer, and the other face of the tape base is coated with a heat-resisting
coating; the
printing ink layer coats the tape base by using a heat melting way, and the
printing ink layer comprises binders,
coloring agents, filler and auxiliaries. A preparation method of the
heat transfer printing
colored tape comprises the steps that the binders, the
coloring agents, the filler and the auxiliaries are fully mixed and dispersed, and then grinded to obtain printing ink layer
coating liquid; the front face of the tape base is coated with the printing ink layer
coating liquid by using a coating
machine; the back face of the tape base are uniformly coated with organic
silicone emulsion or a
polyimide solution through the coating
machine, and the heat-resisting coating is formed through
drying the organic
silicon emulsion or the
polyimide solution. According to the heat
transfer printing colored tape, the heat-resisting coating makes contact with a printing head, and the printing ink layer makes contact with the
label, the printing head generates heat when is operated, and printing ink is dissolved and stamped on the
label through the heat-resisting coating to form characters and images. The heat
transfer printing colored tape can be used on the band-shaped or card-shaped label, and has better scratch resistance and durability.
