Problems solved by technology

[0003] Based on the fact that most of the above three kinds of ribbons use solvent-based colorants in the preparation process, such as butanone, toluene, xylene, butyl ester, and ethyl acetate, most of the thermal transfer ribbons on the market will release during the production process. A large amount of organic solvents will cause serious pollution to the environment and cause great harm to the personnel who prepare and develop ribbons

Abstract

The invention relates to a heat transfer printing water-based ink coloring agent and a preparation method thereof, and belongs to the technical field of printing paint. The heat transfer printing water-based ink coloring agent is prepared from the following raw materials in parts by mass: 40 to 80 parts of water-based resin adhesive, 1 to 50 parts of superfine particle material, 10 to 20 parts of pigment and 0.1 to 2.5 parts of auxiliary agent. The invention further discloses a preparation method of the heat transfer printing water-based ink coloring agent. The invention has the beneficial effects that no organic solvent is involved in the preparation and use processes, no harm is caused to the human body and the environment, the heat transfer ink is suitable for a heat transfer film and a heat transfer ribbon, the heat transfer effect is good, the transferred pattern is clear, and the heat transfer ink has the advantages of scratch resistance, solvent corrosion resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of printing coatings, and in particular relates to a thermal transfer printing water-based ink colorant and a preparation method thereof. Background technique [0002] Thermal transfer printing is a form of graphic printing, which is to pre-coat the required printed layer on polyethylene terephthalate (PET), polybutylene terephthalate (PBT), Thermal transfer ribbons are prepared on substrates such as polyethylene naphthalate (PEN), polyethylene (PE), polypropylene (PP), polyvinyl alcohol (PVA), etc. A printing process that prints the required pattern on the corresponding carrier by pressing. At present, the common thermal transfer ribbons on the market are divided into wax-based ribbons, wax-based and resin-based mixed ribbons, and resin-based ribbons. Among them, wax-based ribbons usually contain a high percentage of wax-based raw materials and are low in price. They are mainly used for Resistant to print...
