Embodiment 1
[0023] Embodiment 1: as figure 1 Shown, the manufacture method of the reflective film with anti-counterfeit function of the present invention is: on the PET carrier film 1 surface that is 75 microns in thickness, coat release agent, release agent is 1% cellulose aqueous solution, and at 90 ℃ Bake for 3 minutes under the same conditions, and dry the moisture in the release agent to form the release agent layer 2; then print the anti-counterfeiting watermark pattern 3, in order to improve the clarity and weather resistance of the pattern, and not affect the reflective effect of the pattern, Use weather-resistant and transparent pigments in the process of printing colored or black inks, and use ink resins based on acrylic modified vinyl chloride resins; then apply acrylic or polyester resins to form surface resin layers 4, with a thickness of 50 Micron, in order to further improve the outdoor weather resistance of the product pattern and ensure that it has the effect of not fadi...

Abstract
The invention relates to a fabricating method of a reflective membrane with anti-fake function, which comprises the following steps: printing patterns on a PET carrier membrane coated with parting medium, coating a resin layer special for the reflective membrane, and removing the PET carrier membrane on the surface layer after completing the next procedure of the reflective membrane. In the invention, anti-fake patterns are embedded into the resin layer by a transferring method and integrated with the resin layer into a whole so that the solvent resistance is strong and the anti-fake patterns can not be removed in a physical or chemical method. The invention has simple production device and process, low cost, and high finished product rate, and is convenient for mass production and popularization; the outdoor weather resisting property is remarkable, and the color is not faded by using for more than 5 years.
Description
technical field [0001] The invention relates to the production of an anti-counterfeit reflective material, in particular to the production process of adding an anti-counterfeit pattern to the reflective film. Background technique [0002] Anti-counterfeiting technology is quite popular and mature, but the anti-counterfeiting technologies used for reflective film mainly include printing anti-counterfeiting and laser anti-counterfeiting. The former requires a large investment in equipment. The current process mostly uses gravure printing technology to print patterns on the inner surface of the resin. Since it is printed on the inner layer of the resin, there are higher requirements for the smoothness of the resin surface and the adhesion between the resin and the pattern. . If the surface of the resin is poor in flatness or has flaws on the surface, the efficiency or yield of production will be greatly reduced. Laser anti-counterfeiting technology is to puncture the metal c...
