Abstract

Disclosed are a coloured dynamic stereoscopic moire image thin film based on micro printing and a preparation method therefor. A moire image thin film comprises a transparent base material layer, a micro lens array layer located at one side of the transparent base material layer and a micro pattern array layer located at the other side of the transparent base material layer. The micro lens array layer comprises several micro lenses arranged in an array. The micro pattern array layer comprises several sets of micro patterns arranged in an array and having different colours. The array arrangement of the micro lenses matches the array arrangement of the micro patterns. The moire image formed by the moire image thin film is characterized by being coloured, dynamic and stereoscopic. In any light environment, an observer can observe a coloured three-dimensional dynamic pattern without any special observation skill.

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,...
