Example Embodiment
[0048] Example 1
[0049] The preparation of a two-dimensional code with double-layer printing response is as follows:
[0050] (1) Generate two-dimensional codes with different information in the two-dimensional code generator, and determine the display order, and then use an inkjet printer to set a quantitative value of 120g / m 2 Print the yellow first-layer QR code on the paper;
[0051] (2) Use dichloromethane to dissolve 1g 1,3,3-trimethyl-6-nitro-indoline spiropyran and 9g polylactic acid, mix mechanically for 30 minutes and mix uniformly, heat to volatilize dichloromethane, Extrude a transparent wire with a diameter of 1.75mm in the extruder at a temperature of 180°C, install the transparent wire on the FDM 3D printer, and print a transparent 2D with a thickness of 0.1mm on the surface of the first layer of the QR code using the 3D printer Code to obtain the double-layered printing response two-dimensional code.

[0054] Example 2
[0055] The preparation of a two-dimensional code with double-layer printing response is as follows:
[0056] (1) Generate two-dimensional codes with different information in the two-dimensional code generator, and determine the display order, and then use an inkjet printer to set a quantitative value of 120g / m 2 Print the first red QR code on the paper;
[0057] (2) Use 5ml of diarylethylene / xylene solution modified with trimethylsilyl group and 1ml of 4-acryloxybenzophenone / xylene solution, mix with each other, mechanically stir for 20min and mix well, then use screen printing The machine prints the second layer of two-dimensional code on the surface of the first layer of two-dimensional code to obtain the double-layered printing response two-dimensional code.
[0058] The color of the backing layer and the first layer of two-dimensional code are gray, the color gray level of the first layer of two-dimensional code is greater than that of the backing layer, the dif...
