Abstract
The disclosure belongs to the technical field of photopolymer materials, and more particularly relates to a dual image storage material as well as a preparation method and application thereof. The dual image storage material is obtained by selective photoreaction of 1 to 50 parts by weight of an organic fluorescent material, 7 to 50 parts by weight of liquid crystal, 0.2 to 10 parts by weight of a photoinitiator and 33 to 67 parts by weight of photopolymerizable monomers. The obtained dual image storage material can present a high-brightness holographic pattern under sunlight and a fluorescent pattern under ultraviolet light in the same spatial position. The presented holographic and fluorescent patterns may be the same or different. The obtained dual image storage material can be used in the field of optical anti-counterfeiting, optical information storage, displays or the like.
