Abstract

The invention provides a heat transfer printing ink ribbon for a metal material. The heat transfer printing ink ribbon for the metal material comprises a base membrane layer, wherein a heat transfer printing ink layer is arranged on one side of the base membrane layer, and a back coating is arranged on the other side of the base membrane layer. The heat transfer printing ink layer comprises, by weight, 20-25% of thermoplastic acrylic resin, 10-20% of E-20 bisphenol A epoxy resin, 5-10% of E-12 bisphenol A epoxy resin, 3-6% of tetra hydro phthalic anhydride, 20-35% of compound wax, 0.5-1% of 2-hydroxy ethyl methacrylate phosphate, 8-15% of coloring agents and 10-20% of solvent. According to the heat transfer printing ink ribbon, application of the heat transfer printing ink ribbon to metal printing media is achieved, the adhesion to metal is good, and the purpose that heat transfer printing operation is directly conducted on the metal printing media is achieved; the scraping resistance is good, printed patterns are clear and complete, and the application range of the heat transfer printing ink ribbon is broadened.

Description

technical field [0001] The invention relates to a thermal transfer ribbon, in particular to a thermal transfer ribbon for metal materials. 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 image quality of thermal transfer printing. Thermal transfer ribbon is a product with a wide range of uses and a very large amount. With the rapid development of my country's information technology and the continuous expansion and deepening of computer applications, people's printing demand for high-speed and high-quality output is increasing. It is difficult to meet the all-round needs of users. Due to the use of high-strength ultra-thin film and high-concentration ink, and the single-use method, the thermal transfer ribbon has high-quality printed characters, long service life of the ribbon, and overcomes ink-jet paper bleeding and is easily soluble in Water and ot...
