Abstract
The present application relates to the technical field of optical film, and discloses an optical imaging film and a preparation method thereof. The optical imaging film comprises: a body having a first surface and a second surface which are opposite to each other; a focusing structure formed on the first surface of the body; and N layers of graphic and text structure which are stacked in sequence on the second surface of the body or inside the body, wherein, each layer of graphic and text structure is located within an imaging range of the focusing structure, and each layer of graphic and text structure in the imaging range can form a suspension image by means of the focusing structure. Through the technical solutions disclosed in the embodiments of the present application, the anti-counterfeiting effect of an imaging film can be improved, and the imaging of the imaging film can present better sense of layering and has more diversified colors.
