Embodiment 1

[0018] Such as figure 1 As shown, the anti-counterfeiting ticket thermal paper is composed of base paper layer 1, precoat layer 2 and color developing layer 3.

[0019] The production process of the base paper layer and the pre-coat is an existing process, and the pre-coat coating composed of calcined kaolin, calcium carbonate, polystyrene hollow sphere resin, calcium stearate, polyvinyl alcohol, starch latex, and additives is adopted. It is uniformly coated on the heat-sensitive base paper by blade coating or curtain coating, and then dried and calendered to form heat-sensitive pre-coated paper.

[0020] The color-developing layer is composed of a color-developing agent, a colorless dye, an anti-counterfeiting paint and an auxiliary paint. Take 80kg of 2-methyl-6-(N-ethyl-N-4-tolylamine) fluorane, 10kg of polyvinyl alcohol, and 10kg of calcium silicate and mix evenly; use a grinder to control the particle size of the paint to 0.5um; Get ground anti-counterfeit paint 5kg, 4-...

Embodiment 2

[0023] On the basis of Example 1, the chromogen is replaced by 4,4'-sulfonyl bis[2-(2-propenyl)]phenol, and the leuco dye is replaced by 2-(2',4'-dimethyl Anilino-3-methyl-6-diethylaminofluorane, the chromogenic material in the anti-counterfeiting coating is replaced by 1,2-benzo-6-(N-ethyl-N-isoamylamine) fluorane, All the other carry out with the step described in embodiment 1.

Abstract

The invention discloses anti-fake ticket thermo-sensitive paper suitable for the fields of entrance tickets, license plates, invoices and special labels. The anti-fake ticket thermo-sensitive paper has the developing function of common thermo-sensitive paper, in addition, after a color development device conducts developing, the black interior and red edge developing anti-fake function is achieved, the large developing area shows the black character pattern, and the edge of the black character pattern shows red. Accordingly, the common anti-fake ticket thermo-sensitive paper easy to distinguish is provided, and the forging behavior of the thermo-sensitive paper can be cracked down in the special field.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeit thermal paper, in particular to an anti-counterfeit thermal paper for tickets, license plates, invoices and special labels. Background technique [0002] Thermal paper is used as a readable information recording material and is widely used in logistics labels, lottery tickets, cash registers, ATMs and other fields. In terms of application effect, the thermal paper on the market displays black text or patterns, and the color developer and leuco dye in the coating of the thermal paper react chemically to develop color through thermal printing and other components, so that it has a record information function. [0003] With the extension of the application field of thermal paper, thermal paper has been extended to the fields of tickets, license plates, invoices and special labels. Because it has a certain economic value, the market hopes that this type of thermal paper will be specific. No...
