Heat transfer printing colored tape capable of being used on band-shaped or card-shaped label and preparation method thereof

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of thermal transfer ribbons in printing consumables, and in particular relates to a thermal transfer ribbon that can be used on tape-shaped or card-shaped labels and a preparation method thereof. Background technique [0002] Thermal transfer ribbon is a necessary consumable material for thermal transfer printing, and it is also the core material that determines the quality of thermal transfer printing. Thermal transfer ribbon transfers the ink layer on the ribbon to the plastic through heat and pressure. It is a kind of printing consumables on materials such as paper, composite film, etc. It uses temperature and pressure to dissolve the ink on the ribbon, and then hot stamps the ink on the label. It is suitable for printing identification and marking information such as production date, batch number, and weight. , which can print characters clearly. The most commonly used thermal transfer ribbon in the pr...
