Abstract

A colored, dynamic, and amplified security film includes a micro lens array layer, a base material layer, and a micro graphic layer. The layers meet the condition of Moore amplified imaging; the micro graphic layer is formed by a background area and a graphic area; the graphic area is distributed in the background area; the micro graphic layer includes a semi-transparent and semi-reflective metal layer, a medium layer, and a metal film layer successively from top to bottom; the metal film layer is of a planar structure; the thickness of the medium layer in the graphic area is greater than the thickness of the medium layer in the background area; and the thicknesses of semi-transparent and semi-reflective metal layers are consistent.
