▎ 摘　　要

NOVELTY - An anti-fake easy-tearing film with light-changing effect comprises heat-sealing protective layer, anti-fake label, printing layer, substrate layer and adhesive layer that are jointed. The printing layer is printing layer with light change effect. The substrate layer is polyester film. The printing layer with light change effect comprises 3-8 pts. wt. graphene, 1-5 pts. wt. ferrous chloride, 1-3 pts. wt. copper chloride, 10-25 pts. wt. organic silicon resin, 5-10 pts. wt. isocyanate, 5-10 pts. wt. tannic acid, 1-3 pts. wt. tackifier, 3-5 pts. wt. coupling agent, 15-20 pts. wt. water and 20-25 pts. wt. acetone. USE - Anti-fake easy-tearing film with light-changing effect. ADVANTAGE - The film can keep good tensile strength, and has good uniformity, flexibility and easy tearing and excellent anti-aging performance. The method is simple and feasible. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing anti-fake easy-tearing film with light-changing effect comprising dispersing graphene in water, dispersing isocyanate and tannic acid in acetone, adding tackifier and coupling agent into acetone, heating at 80-100degrees Celsius and keeping temperature for 1-2 hours, mixing graphene dispersion liquid with acetone, adding ferrous chloride, copper chloride and organic silicon resin, uniformly stirring to obtain printing liquid with light change effect, installing substrate layer on unreeling frame of printing machine, printing of printing liquid with light change effect on surface of substrate layer through printer, drying substrate layer, attaching anti-fake label on printing layer, using dry compound machine, coating adhesive on other side of base layer to form adhesive layer, and thermally pressing heat-sealing protective layer on anti-fake label.
