Transparent hidden holographic identification and manufacturing method thereof

Abstract

The invention provides a transparent hidden holographic identification and a manufacturing method thereof. The transparent hidden holographic identification structurally and sequentially comprises a silicone oil base layer, a pressure-sensitive adhesive sticker layer, a separable transparent layer, a transparent holographic information layer and a transparent base material layer from inside to outside. The transparent base material layer is coated with a transparent imaging resin layer, the holographic information layer is formed on the transparent imaging resin layer through die pressing, the holographic information layer is coated with the separable transparent layer, the silicone oil base layer is coated with the pressure-sensitive adhesive sticker layer, and then the processed base material layer and the silicone oil base layer are composited to form the transparent hidden holographic identification through die-cutting forming. The transparent hidden holographic identification manufactured by means of the manufacturing method has the following advantages that the identification is colorless and transparent and can serve as a printing base material, the hidden holographic information layer is shown again after the identification is uncovered, holographic contents can be directly and secondarily distinguished with naked eyes, an identification structure is destroyed and cannot be restored, and holographic images have hiding property, non-duplication property and higher anti-counterfeiting performance.

Description

technical field [0001] The invention relates to a sign product, in particular to a transparent hidden holographic sign and a manufacturing method thereof. Background technique [0002] Laser holographic technology was hailed as one of the most advanced anti-counterfeiting technologies before 2000. Through the three-dimensionality of laser holographic patterns, angle changes, and the characteristics of hidden information, it has high anti-counterfeiting strength. However, with the development of holographic anti-counterfeiting technology, the production of holographic products has evolved into computer software design and computer automatic lithography plate making, which has greatly reduced the entry requirements of the holographic anti-counterfeiting industry. As long as the investment in equipment can be produced, imitation has become more easy. For example, the Chinese invention patent with application number 200810039808.5 discloses a kind of anti-counterfeiting film an...

Problems solved by technology

For example, the Chinese invention patent with application number 200810039808.5 discloses a kind of anti-counterfeiting film and its preparation method. The anti-counterfeiting film disclosed in this technical scheme uses a photopolymerizable information layer to realize the display of anti-counterfeiting information. Although it can achieve a certain degree of anti-counterfeiting function, However, this anti-counterfeiting film is only used as an anti-counterfeiting mark through simple information display, it only has a single anti-counterfeiting structure, and is easy to imitate, so it cannot have a very high anti-counterfeiting effect
