Multi-layer thermal transfer ribbon and manufacturing method thereof

Abstract

The invention relates to a multi-layer thermal transfer ribbon and a manufacturing method thereof, and the multi-layer thermal transfer ribbon comprises a membranous base band, a heat-resistant printing ink layer and a heat transfer printing ink layer, wherein the heat-resistant printing ink layer is coated on one side of the base band, the heat transfer printing ink layer is coated on the other side of the base band, the heat transfer printing ink layer comprises a stripping printing ink layer and an adhesive printing ink layer, the stripping printing ink layer is directly coated on the surface of the base band, the adhesive printing ink layer is coated on the stripping printing ink layer, printing ink in the striping printing ink layer is hot-melting type printing ink, and the printing ink in the adhesive printing ink layer is the hot-melting type printing ink or solvent type printing ink. The heat transfer printing ink layer of the multi-layer mixed-based ribbon can be easily completely stripped off the base band, and the great adhesive ability is realized on a smooth medium; in addition, the multi-layer thermal transfer ribbon further has the advantages of high resolution, clear printing, anti-friction property, moisture resistance, chemical corrosion resistance, environment friendliness and the like.

Description

technical field [0001] The invention relates to a thermal transfer carbon ribbon, in particular to a multilayer thermal transfer ribbon and a manufacturing method thereof. Background technique [0002] With the advent of the information society of economic globalization, information networking, internationalization of life, and localization of culture, the barcode and barcode technology, which originated in the 1940s, researched in the 1960s, applied in the 1970s, and popularized in the 1980s, are like a An economic information link organically connects manufacturers, exporters, wholesalers, retailers and customers around the world. With the development of computer technology and thermal transfer printers, the application of barcode ribbons has also developed rapidly, and has gradually penetrated into many technical fields. [0003] The thermal transfer imaging method was invented by Mille in 1953. As a non-contact printing computer peripheral output device, it has become a...

Problems solved by technology

[0008] The world's mainstream mixed-base barcode ribbons all use solvent-based coating methods. The solvents used are generally organic solvents such as gasoline, toluene, xylene, ethyl acetate, butyl acetate, methyl ethyl ketone, and cyclohexanone. pose a great threat to human health and also cause certain pollution to the environment

[0009] At present, most of the products on the market have only one layer of thermal transfer ink layer in their coating. During the printing process, there is often such a problem that the ink on the carbon ribbon cannot be separated from the base tape and attached to the printing medium, and the ink is not compatible with the printing process. The adhesion of the medium is not good, and the printed graphics are easily damaged by external force. This is because the ink layer needs to have good performance of peeling from the base tape and good performance of bonding with the printing medium. It is difficult to realize the two in the same body, and its production process is more complicated

In addition, the reasons for the problems of the ink layer in the existing products that are not scratch-resistant and have poor adhesion to smooth media include: the content of resin in the components is too low, the content of wax is too high, and the wax used The content of straight chain hydrocarbons is low, and its hardness is small. The overall hardness and viscosity of the ink layer cannot meet the requirements for use, resulting in imprinting that is not scratch-resistant and poor in acid and alkali resistance.
