Abstract
Disclosed are an optical anti-counterfeiting element and a manufacturing method thereof, and an anti-counterfeiting product. The optical anti-counterfeiting element includes a micro lens array layer and a micro graphic-text array layer; the micro graphic-text array layer includes a micro graphic-text area and a micro graphic-text background area; surface undulation shapes of the micro graphic-text area and the micro graphic-text background area are different; and/or a height difference is set for the micro graphic-text area and the micro graphic-text background area, so that a graphic-text area and/or a graphic-text background area imaged by the micro lens array layer and the micro graphic-text array layer under sampling synthesis have different visual features. In particular, with a change in an observation angle, a graphic-text and/or a graphic-text background changes from one color to another color, thereby improving an anti-counterfeiting capability.
