Abstract

The invention provides a product with a holographic pattern and a manufacturing method thereof. The product comprises a substrate and a holographic pattern layer, wherein the substrate and the holographic pattern layer made of the same material form an integrated structure. The method comprises the following steps: recording a required pattern onto a photographic plate through laser holography and manufacturing an optical mask plate with the holographic pattern; copying the holographic pattern on the optical mask plate and forming a metal plate with the holographic pattern; and transferring the holographic pattern on the metal plate onto the surface of the substrate by a mould pressing method, and forming the holographic pattern layer. Compared with the prior TPU product with the holographic pattern, the product with the holographic pattern is made of a material with better handfeel. Compared with the manufacturing method for the TPU product with the holographic pattern, the manufacturing method provided by the invention decreases working procedures of the manufacture of laser release paper or a laser release film and hot-pressing release transfer, and simplifies manufacturing process.

Description

technical field [0001] The invention relates to a product with holographic patterns and a manufacturing method thereof. Background technique [0002] Holographic technology has unique characteristics such as good three-dimensional effect, colorful and gorgeous, and dynamic peripheral vision, so it has attracted widespread attention since it came out. With the rapid development of holographic technology, molded holographic technology has also emerged as the times require. It is a comprehensive modern high-tech integrating multiple disciplines such as optics, electronic machinery, surface chemistry, arts and crafts and relief printing. Molded holographic products have the advantages of unique functions, low price, automatic mass production, and a wide range of applications. They are mainly used in anti-counterfeiting, decoration and packaging. The types include laser holographic film, laser holographic paper, etc. The holographic pattern is transferred or bonded to the surfac...
