The invention provides a fragile anti-fake label with fibers arrayed randomly and directionally and a preparation method of the fragile anti-fake label, and belongs to the field of anti-fake labels. The anti-fake label comprises three layers which sequentially include release paper, a self-adhesive layer and an anti-fake coating, wherein the surface of the self-adhesive layer is coated with water-based ink, and then drying is conducted to obtain the anti-fake coating; the water-base ink is prepared from water-base resin, a dispersing agent, a defoaming agent, a leveling agent, a thickening agent, titanium dioxide and calcium carbonate, and fiber-shaped objects can be further included in the water-based ink. By adding the water-base resin with a large molecular weight and a chain structure,the resin is arrayed into a membrane through a fiber mode during membrane forming, the added fiber-shaped objects are arrayed in a selected direction, during random coating, the fiber-shaped objectsare arrayed more uniformly, and the prepared anti-fake label has generality and is convenient to apply and popularize. Meanwhile, the fragile anti-fake label has the advantages of having strong threedimension and a touch feeling, being provided with the fibers capable of being touched, and being capable of being used for writing and fragile; recognizing is easy, and the anti-fake degree is high.
