Embodiment 1

[0029] Dissolving vinyl chloride-vinyl acetate copolymer and ethylene-vinyl acetate copolymer in a methyl ethyl ketone solvent in a ratio of 5:1 is prepared as a resin solution with a concentration of 10%; get 100 parts of resin solution, and 5 parts of DegassaPrintex 25 charcoal Black and 0.2 parts of PA113 pigment dispersant, 0.1 part of Deuchem-457 leveling agent, 0.5 parts of BYK-052 defoamer, 0.5 parts of DEGUSSA HUIS adhesion promotion resin are mixed, and after being dispersed by a sand mill, the ink is obtained layer coating solution; the ink layer coating solution is passed through the gravure coating machine to think that every 2g / m 2 The coating amount is coated on the film tape base with a thickness of 4.5 μm coated with a heat-resistant back layer on the back to obtain a thermal transfer ribbon.

Embodiment 2

[0031] Dissolving vinyl chloride-vinyl acetate copolymer and polyvinyl acetate at a ratio of 3:1 in methyl ethyl ketone solvent was prepared as a resin solution with a concentration of 5%. Take 50 parts of resin solution, with 5 parts of Degassa Printex 25 carbon black and 0.2 parts of PA113 pigment dispersant, 0.2 parts of Deuchem-457 leveling agent, 0.3 parts of BYK-052 defoamer, 0.3 parts of DEGUSSA HUIS Focus on promoting the mixing of resins, and after being dispersed by a sand mill, the ink layer coating solution is obtained; the ink layer coating solution is passed through a gravure coater to 2 The coating amount is coated on the film tape base with a thickness of 4.5 μm coated with a heat-resistant back layer on the back to obtain a thermal transfer ribbon.

Embodiment 3

[0033] Vinyl chloride-vinyl acetate copolymer, ethylene-vinyl acetate copolymer and polyvinyl acetate are dissolved in ethyl acetate solvent at a ratio of 80:15:5 to prepare a mixed resin solution with a concentration of 30%. Take 60 parts of resin solution, with 10 parts of Degassa Printex 25 carbon black and 1 part of PA113 pigment dispersant, 2.5 parts of Deuchem-457 leveling agent, 2.5 parts of BYK-052 defoamer, 4 parts of DEGUSSA HUIS attached Focus on promoting the mixing of resins, and after being dispersed by a sand mill, the ink layer coating solution is obtained; the ink layer coating solution is passed through a gravure coater to 2 The coating amount of is coated on a 5μm thick film tape base coated with a heat-resistant back layer on the back to obtain a thermal transfer ribbon.

Abstract

The present invention relates to a kind of heat transfer printing color ribbon and its preparation process. The heat transfer printing color ribbon consists of base belt, ink layer and heat resistant back layer. The ink layer consists of adhesive, coloring agent and assistant, and the adhesive consists of two or more kinds one resin. The preparation process includes the following steps: dissolving resin in solvent to obtain 5-30 % concentration resin solution; mixing and dispersing resin solution, coloring agent and assistant to obtain ink layer coating liquid; and coating the ink layer coating liquid with a intaglio coating machine onto the film base belt with heat resistant back layer to obtain the heat transfer printing color ribbon. The preparation process is simple and low in cost, and the produced heat transfer printing color ribbon is suitable for heat transfer printing on polyester label.

Description

technical field [0001] The invention relates to a recording material for printing technology, in particular to a thermal transfer ribbon and a preparation method thereof. Background technique [0002] The thermal transfer ribbon is a necessary consumable material for the thermal transfer printing method, and it is also the core device that determines the imaging quality of the thermal transfer printing. The application of thermal transfer printing technology has developed rapidly in recent years, and it has become a commonly used efficient and convenient on-site instant printing technology. Its working principle is that the signal drives the heating dot matrix on the thermal transfer head, and the heat is transferred to the thermal transfer ink layer through the substrate to melt and transfer to the image receiving medium, and the monochrome image or text can be output through the ribbon. The thermal transfer printing method has high resolution, clear printed text and image...
