Embodiment 1

[0057] The multi-color hand temperature reversible thermochromic thermal transfer ribbon provided in this example is composed of three parts, from top to bottom: the adhesive layer coated with modified silicone, the middle layer formed by the carrier PET film layer, and the lowermost release layer, under the release layer is an ink layer formed by reversible thermochromic ink;

[0058] When the reversible thermochromic ink is specifically prepared, in terms of parts by weight, the material composition is:

[0059] 30 parts of polyurethane-acrylate composite resin emulsion;

[0060] 20 parts of thermochromic microcapsules (mass ratio, black to blue: blue to purple = 1:1);

[0061] 1 part of filler mica powder;

[0062] 0.5 parts of anti-sedimentation agent F02 dispersant;

[0063] 0.6 parts of defoamer SP-20 acetylenic diol type nonionic surfactant;

[0064] Leveling agent EL-1006 fluorosurfactant 0.8 parts;

[0065] 25 parts of water.

[0066] During concrete preparation...

Embodiment 2

[0100] The carbon ribbon product provided by the present embodiment, its preparation method is the same as embodiment 1, only adjusts as follows with respect to ink formula:

[0101] 60 parts of polyurethane-acrylate composite resin emulsion; 20 parts of thermochromic microcapsules (mass ratio, black to blue: blue to purple=1:1);

[0102] Filler mica powder 2 parts;

[0103] 0.8 parts of anti-sedimentation agent F02 dispersant;

[0104] 0.6 part of antifoaming agent acetylene glycol type nonionic surfactant;

[0105] Leveling agent EL-1006 fluorosurfactant 0.3 parts;

[0106] 37 parts of water.

[0107] After printing the PET label with the carbon ribbon prepared in this embodiment, the detection method for the discoloration performance of the printed writing and the friction resistance and sweat resistance of the writing is the same as that of Example 1. The detection results are as follows:

[0108] The temperature from black to blue is 33°C, the color change time is 36....

Abstract

The invention belongs to the technical field of thermal transfer printing, and particularly relates to a multi-color hand temperature reversible thermochromic thermal transfer ribbon and a preparation method thereof. The thermal transfer ribbon is composed of three parts, namely a back adhesive layer coated with modified organic silicon, a middle layer and a lowest release layer from top to bottom in sequence, and an ink layer formed by reversible thermochromic ink is arranged below the release layer. According to the thermal transfer ribbon product provided by the invention, the surface of the ink layer is flat, fine and smooth, after the thermal transfer ribbon product is applied, handwritings on a printing material are various in color change, high in color change sensitivity, good in color change reversibility, good in friction resistance, perspiration-resistant and grease-pollution-resistant, and the thermal transfer ribbon product has better application value for enriching the types of thermal transfer ribbons and improving the packaging and printing quality of related products.

Description

technical field [0001] The application belongs to the technical field of thermal transfer printing, and in particular relates to a multi-color hand temperature reversible thermochromic ribbon and a preparation method thereof. Background technique [0002] In the prior art, the color of the writing on the thermal transfer ribbon commonly used in the market is fixed after transfer. Therefore, in practical applications, customers need to select the corresponding color ribbon for printing application according to the preset handwriting color. On the other hand, since the pattern on the product packaging is static, only information is recorded and displayed, and there is no interaction with consumers. Therefore, in the actual consumption experience, consumers cannot experience the joy of interaction from the product packaging. On the other hand, based on the technical requirement of color anti-counterfeiting, it is obviously of great technical significance to provide a thermal t...
