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.
本公开属于光聚合物材料技术领域,尤其涉及一种双图像存储材料及其制备方法和应用。该双图像存储材料是由 1 至 50 份(按重量计)有机荧光材料、7 至 50 份(按重量计)液晶、0.2 至 10 份(按重量计)光
引发剂和 33 至 67 份(按重量计)可光聚合单体通过选择性光反应得到的。所获得的双图像存储材料可在同一空间位置呈现出阳光下的高亮度全息图案和紫外线下的荧光图案。所呈现的全息图案和荧光图案可以相同,也可以不同。所获得的双图像存储材料可用于光学防伪、光学信息存储、显示器等领域。
