Title:
DOUBLE IMAGE STORAGE MATERIAL, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/223074
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of photopolymerizable materials, and more specifically, relates to a double image storage material, a preparation method therefor and the use thereof. The double image storage material is obtained by a selective photoreaction of 1-50 parts by weight of an organic fluorescent material, 7-50 parts by weight of a liquid crystal, 0.2-10 parts by weight of a photoinitiator and 33-67 parts by weight of a photopolymerizable monomer. The obtained double image storage material may not only present a high brightness holographic pattern in daylight, but may also present a fluorescent pattern excited by an ultraviolet light at the same space position. The presented holographic pattern and fluorescent pattern may be the same, and may also be different. The obtained double image storage material can be used in fields such as optical anti-counterfeiting, optical information storage, and displays.
