Abstract

The invention discloses a colored dynamic three-dimensional moire image thin film based on micro printing and a preparation method of the colored dynamic three-dimensional moire image thin film. The moire image thin film comprises a transparent base material layer, a micro-lens array layer located on one side of the transparent base material layer, and a micro-pattern array layer located on the other side of the transparent base material layer. The micro-lens array layer comprises a plurality of micro-lenses arranged in an array. The micro-pattern array layer comprises a plurality of micro-patterns which are arranged in an array and are different in color. The array arrangement of the micro-lenses is matched with the array arrangement of the micro-patterns. The moire image formed by the moire image thin film is characterized by being colored, dynamic and three-dimensional, and an observer can directly observe a colored three-dimensional dynamic pattern without any special observation skills under any luminous environment.

Description

technical field [0001] The invention relates to the technical field of public optical vision security and anti-counterfeiting, in particular to a microprint-based color dynamic three-dimensional moiré image film and a preparation method thereof. Background technique [0002] The optical anti-counterfeiting technologies mainly used in the prior art are divided into three categories: public anti-counterfeiting, professional anti-counterfeiting and third-line anti-counterfeiting. Public anti-counterfeiting mainly adopts the main scene pattern, multi-channel and dynamic technology. Most professional anti-counterfeiting uses miniature images and text, which can be clearly distinguished with a high-power magnifying glass with its own light source. Three-line anti-counterfeiting mainly includes diffraction units and various coding techniques. Among them, the characteristic of public anti-counterfeiting technology is that under normal conditions, without the aid of any instrument,...
