Description

Light becomes radium-shine paper

Technical Field

The utility model relates to a radium-shine material technical field refers in particular to a light becomes radium-shine paper.

Background

The laser paper is high-end paper with laser holographic pattern or text signal loaded onto the surface of aluminized paper in mold pressing mode. It organically combines multiple high and new technologies such as special plate making, computer photoetching, precise electroforming, laser holographic die pressing, fine chemical engineering, high-precision stripping and the like, and is widely applied to packing materials such as cigarettes, foods, medicines and the like and products such as anti-counterfeiting marks and the like due to gorgeous colors and decorative effects. For example, various laser papers disclosed in chinese patent documents CN 209779338U, CN 209779339U and CN 207391932U.

Photochromic refers to the fact that under the action of light with certain wavelength and intensity, the molecular structure of some compounds is changed, so that the absorption peak value of the compounds to the light, namely the corresponding change of the color is caused, and the change is generally reversible. Photochromism is generally applied to the fields of optical information storage, holographic materials, protection and decoration materials, camouflage materials, anti-counterfeiting materials and the like.

Along with the improvement of living standard, people pursue more and more beautiful fashion and individuality, and the simple laser paper serving as wrapping paper or anti-counterfeiting paper cannot meet the aesthetic requirements of people. Meanwhile, the paper with the laser effect and the photochromic effect can improve the appearance beautification and the grade of the packing paper and the technical content of the anti-counterfeiting paper. However, the laser paper and the optically variable paper produced in the industry at present are produced separately, are independent and simple, and a product which integrates laser and optically variable effects into a whole is not available for a while, namely, the product has the diffraction effect specific to laser and the optically variable effect specific to an optically variable material on a piece of paper.
