Embodiment Construction

[0011] The invention discloses a black-to-green color-changing thermal transfer carbon belt, comprising: a BOPET film, a heat-resistant coating, a release layer, and an ink layer. The outer side of the BOPET film is coated with a heat-resistant coating. The BOPET The inner side of the film is coated with a release layer, and the outer side of the release layer is coated with an ink layer.

[0012] The heat-resistant coating coated on the outside of the BOPET film is composed of the following raw materials in parts by weight: solvent (butanone) 92%-95%, silicone 3%-5%, curing agent 0.2%-0.5%, and the The coating thickness of the heat-resistant coating is 0.1-0.5 μm.

[0013] The release layer coated on the inside of the BOPET film is composed of the following raw materials in parts by weight: solvent (toluene) 75%-85%, card wax 5%-8%, candelilla wax 3%-5%, montan wax 2%-4%, and the coating thickness of the release layer is 0.5-1.0 μm.

[0014] The ink layer coated on the outs...

Abstract

The invention discloses a black-to-green color-changing thermal transfer carbon belt, which comprises: a BOPET film, a heat-resistant coating, a release layer, an ink layer, a heat-resistant coating on the outside of the BOPET film, and a coating on the inside of the BOPET film. A release layer is covered, and an ink layer is coated on the outside of the release layer. The invention has the anti-counterfeiting function of turning black into green, which is convenient for distinguishing the authenticity of tickets, official documents and products, and improves the anti-counterfeiting degree.

Description

technical field [0001] The invention relates to a thermal transfer carbon ribbon, in particular to a black-to-green color-changing thermal transfer ribbon, which is applied to the anti-counterfeiting fields of tickets, official documents and products. Background technique [0002] With the rapid development of my country's productivity and information technology, printing work can be seen everywhere in people's daily work and life. Printed labels such as tickets, official documents and products are forged, causing unnecessary troubles. Therefore, the traditionally used thermal transfer ribbons do not have anti-counterfeiting functions. A color-changing thermal transfer ribbon that can effectively prevent counterfeiting appears. become all the more urgent. Contents of the invention [0003] In order to solve the defects of the existing technical solutions, the present invention discloses a black-to-green color-changing thermal transfer ribbon with the anti-counterfeiting fun...
