Abstract

The invention relates to the technical field of thermosensitive paper, and discloses three-proof thermosensitive paper for improving clarity of printing patterns. The three-proof thermosensitive papercomprises a base paper layer. The top surface of the base paper layer is bonded with a thermosensitive coating layer, the top surface of the thermalsensitive coating layer is bonded with a protectivelayer, and the top surface of the protective layer is bonded with an adsorption layer. The thermosensitive coating layer comprises a developing agent, a dye, a pigment and an adhesive. The bottom surface of the developing agent is bonded to the top surface of the base paper layer. The top surface of the developing agent is provided with the dye, the top surface of the dye is provided with the pigment, and the developing agent and the dye, and the dye and the pigment are bonded by the adhesive. By means of the three-proof thermosensitive paper for improving clarity of the printing patterns, the colour rendering effect of the three-proof thermosensitive paper is improved, the waterproof, fire-proof, anti-static and abrasion-resistant properties of the three-proof thermosensitive paper are enhanced, at the same time, the adsorptive performance of the three-proof thermosensitive paper to ink is improved, and the clarity of the printing patterns of three-proof thermosensitive paper is improved by the combined action of the thermosensitive coating layer and the adsorption layer.

Description

technical field [0001] The invention relates to the technical field of three-proof heat-sensitive paper, in particular to a three-proof heat-sensitive paper that improves the definition of printed patterns. Background technique [0002] With the rapid development of e-commerce, thermal paper electronic surface sheets not only require good water resistance, oil resistance, ethanol resistance and other properties, but also have higher and higher requirements for fire prevention, anti-static and printing ink absorption. [0003] At present, scratch resistance and printing adaptability are mutually restrictive and contradictory. The scratch resistance of three-proof paper is usually achieved by increasing the coating amount of the top coat or reducing the amount of filler used while increasing the adhesive. The reduction of filler Weaken the ink absorption of the top coat layer, which will easily lead to low ink volume and insufficient printing blackness when printing with the s...
