High-resolution thermal transfer ribbon and preparation method thereof

Abstract

The invention discloses a high-resolution thermal transfer ribbon which comprises a ribbon base, a thermal transfer ink layer and a thermal resisting coating. One side of the ribbon base is coated with the thermal transfer ink layer, and the other side of the ribbon base is coated with the thermal resisting coating. The thermal transfer ink layer is prepared from, by weight, 28-32 parts of lignite wax, 45-50 parts of carnauba wax, 14-17 parts of carbon black, 12-15 parts of soldering iron black, 4-8 parts of kaolin, 1-3 parts of montmorillonoid, 2.5-3.5 parts of aluminum phosphate, 4-6 parts of DCPD resin, 1-2 parts of methyl silicone oil and 1-5 parts of ethyl acetate. The thermal resisting coating is prepared from, by weight, 9-15 parts of acrylic resin and 85-90 parts of polyimide. The invention further discloses a preparation method of the high-resolution thermal transfer ribbon. The high-resolution thermal transfer ribbon is good in adhesive force, clear in print, resistant to scraping and wide in market prospect.

Description

technical field [0001] The invention relates to the technical field of thermal transfer ribbons, in particular to a high-resolution thermal transfer ribbon and a preparation method thereof. Background technique [0002] 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 other defects, the thermal transfer method does not have any requirements for printing media, and can be printed on plain paper, recycled p...

Problems solved by technology

At present, the ribbons used in many fields (such as the ribbons used for tickets and supermarkets) require the printed characters to have high resolution and no rough edges. Many existing ribbons on the market cannot meet this demand. There are defects such as insufficient adhesion of printed characters, insufficient printing clarity, poor scratch resistance, and blurred writing after scratching. There are also a small number of ribbons with clear printing and good scratch resistance on the market, but these ribbons are all imported , costly
