Problems solved by technology

[0009] so either Figure 13 and Figure 14 The structure in the manual is still the preparation method disclosed on pages 29-30 of the manual. The display image of the microlens and the pattern layer must be provided with an optical spacer layer. Lens and pattern layer; but it is this kind of structure that makes such a thick overall structure extremely unfavorable for cutting off in time during high-speed hot stamping
In addition, transparent substrates tend to have good mechanical properties, which is also not conducive to the cut-off requirements of hot stamping

Abstract

The embodiment of the present application discloses an imaging film and a preparation method thereof. The imaging film comprises: a body made of the same polymer; a focusing structure is formed on a surface of the body; a graphic structure is formed inside the body, and the graphic structure passes through the focusing structure imaging. The technical solutions provided by the embodiments of the present application can reduce the thickness of the imaging film, and facilitate the transfer of the imaging film.

Description

technical field [0001] The invention relates to the technical field of optical films, in particular to an imaging film and a preparation method thereof. Background technique [0002] Moiré technology is a compelling new class of visual security technology. It utilizes the focusing effect of the microlens array to magnify the micropattern efficiently, and realizes the pattern with a certain depth of field and presents a peculiar dynamic effect. [0003] A film with microlenses in the prior art includes a substrate, microlenses and a pattern layer. Such films first contain a substrate resulting in increased thickness, and the patterned layer is exposed or requires a protective layer. [0004] Patent document 200480040733.2 discloses a microlens array security element applied to window security threads of valuable securities such as banknotes. Its basic structure is: a periodic microlens array is set on the upper surface of the transparent base layer, and a corresponding per...
