The invention discloses a safety film with a dynamic three-dimensional effect, which comprises a
microlens array layer, a substrate layer and a micro graphic layer. The micro graphic layer comprises at least six micro-
graphics; and when the safety film is used, the micro graphic layer is arranged near the focal plane of the
microlens array layer. The safety film is characterized in that the central coordinates of each
microlens in the microlens array layer are distributed at random in the microlens array layer, and the microlenses in the microlens array layer correspond to the micro-
graphics in the micro graphic layer. Due the use of the Moore amplification technology and the microlenses, the invention realizes multiple unique visual effects, reduces the process flow, and can be directly manufactured on the PET, PMMA, PC and other
organic film materials in addition to
ultraviolet imprinting. Moreover, the safety film has high performance.
