Embodiment 1

[0045] This embodiment provides a two-color inkless printing paper, including a paper base, a low-melting point thermal ink coating, and a high-melting thermal ink coating coated between the paper base and the low-melting thermal ink coating;

[0046] Among them, the low-melting point thermal ink coating is coated with a low-melting thermal ink liquid. It is mixed with 6 parts by mass of Tinuvin-123; the low-melting point thermal ink in the low-melting point thermal ink liquid is made up of 10 parts by mass of GL-05 polyvinyl alcohol, 5 parts by mass of red heat-sensitive dye of scarlet pigment, and BYK-190 dispersant 2 parts by mass and 83 parts by mass of water are mixed;

[0047]The high melting point thermal ink coating is made of high melting point thermal ink liquid. 3 parts by mass of the anti-ultraviolet agent and 6 parts by mass of the anti-ultraviolet additive of Tinuvin-123; the high-melting point thermal ink in the melting point thermal ink liquid is made of 10 pa...

Embodiment 2

[0067] The difference between this example and Example 1 is that the low melting point thermal ink liquid is obtained by taking 40 parts by mass of low melting point thermal ink, 60 parts by mass of color developing ink, 2 parts by mass of Tinuvin-1130 anti-ultraviolet additive and Tinuvin- 123 anti-ultraviolet additives are mixed with 4 parts by mass; the low-melting point thermal ink in the low-melting point thermal ink liquid is composed of 10 parts by mass of polyvinyl alcohol of GL-05, 3 parts by mass of red thermal dye of scarlet pigment, JYDR- 7 parts by mass of red heat-sensitive dye, 2 parts by mass of dispersant of BYK-190 and 83 parts by mass of water;

[0068] The high melting point thermal ink liquid is mixed with 40 parts by mass of high melting point thermal ink, 60 parts by mass of color developing ink, 3 parts by mass of Tinuvin-1130 anti-ultraviolet additive and 6 parts by mass of Tinuvin-123 anti-ultraviolet additive In the described melting point thermal in...

Embodiment 3

[0081] The difference between this example and Example 1 is that the low melting point thermal ink liquid is obtained by taking 40 parts by mass of low melting point thermal ink, 60 parts by mass of color developing ink, 2 parts by mass of Tinuvin-1130 anti-ultraviolet additive and Tinuvin- 123 anti-ultraviolet additives are mixed with 4 parts by mass; the low-melting point thermal ink in the low-melting point thermal ink liquid is composed of 10 parts by mass of polyvinyl alcohol of GL-05, 3 parts by mass of red thermal dye of scarlet pigment, JYDR- 7 parts by mass of red heat-sensitive dye, 2 parts by mass of dispersant of BYK-190 and 83 parts by mass of water;

[0082] The high melting point thermal ink liquid is mixed with 40 parts by mass of high melting point thermal ink, 60 parts by mass of color developing ink, 2 parts by mass of Tinuvin-1130 anti-ultraviolet additives and 4 parts by mass of Tinuvin-123 anti-ultraviolet additives ; In the described melting point therma...

Abstract

The invention relates to double-color inkless printing paper and a preparation method thereof, and belongs to the technical field of printing. The double-color inkless printing paper comprises a paper base, a low-melting-point heat-sensitive ink coating and a high-melting-point heat-sensitive ink coating, wherein the space between the paper base and the low-melting-point heat-sensitive ink coating is coated with the high-melting-point heat-sensitive ink coating; wherein the low-melting-point heat-sensitive ink coating is formed by coating a low-melting-point heat-sensitive ink liquid, and the low-melting-point heat-sensitive ink liquid is formed by mixing polyvinyl alcohol, a red heat-sensitive dye, a dispersing agent, water, developing ink and an anti-ultraviolet auxiliary agent; the high-melting-point heat-sensitive ink coating is formed by coating a high-melting-point heat-sensitive ink liquid, and the high-melting-point heat-sensitive ink liquid is formed by mixing polyvinyl alcohol, black dye, a dispersing agent, water, developing ink and an anti-ultraviolet aid. The invention also discloses a preparation method of the two-color inkless printing paper. The anti-ultraviolet additive is added, so that the ultraviolet weather resistance of the inkless printing paper under the temperature and humidity change is effectively improved, and the effective retention time of a printed pattern is prolonged.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a two-color inkless printing paper and a preparation method thereof. Background technique [0002] Inkless printing paper can only quickly print black graphics and text, and is widely used in logistics express, labels, lottery, supermarkets, banks and other industries. [0003] The types of printers are divided into dot matrix printers, inkjet printers and laser printers. They all need to match the corresponding printing materials when printing: dot matrix printer matching ribbon, inkjet printer matching ink or integrated ink cartridge, laser printer matching toner Or toner cartridges, so the printing materials need to be replaced regularly, and the used waste ribbons, ink cartridges or toner cartridges are not easy to be recycled, causing great pollution to the environment. In order to completely eliminate the pollution of waste printing materials to the environment, the ink c...
