High-temperature-resistant/wear-resistant anti-counterfeiting hot stamping film and preparation method thereof

Abstract

The invention provides a high-temperature-resistant / wear-resistant anti-counterfeiting hot stamping film and a preparation method thereof, so as to solve the technical problems that in the prior art,an alumite coating is poor in stability, a hot stamping film is poor in scratch resistance, high-temperature hot stamping cannot be achieved, hot stamping patterns are rough, and the service life is short. The high-temperature-resistant / wear-resistant anti-counterfeiting hot stamping film comprises a base layer, a release layer, a high-temperature-resistant layer, an anti-counterfeiting layer, a chromium metal wear-resistant layer and a glue layer which are arranged in sequence. By implementing the technical scheme of the invention, the anti-counterfeiting layer is manufactured by using high-temperature-resistant resin and a heat transfer printing technology, so that a fine microstructure can be realized, and the hot stamping film has a high-temperature-resistant function; the chromium metal wear-resistant layer produced by sputtering has good surface gloss, corrosion resistance and scratch resistance; and the ultraviolet-resistant glue layer is used, so that the hot stamping film hasan ultraviolet-resistant function, and the service life of the hot stamping film is prolonged.

Description

Technical field [0001] The invention relates to the field of hot stamping films, in particular to a high temperature / wear-resistant anti-counterfeiting hot stamping film and a preparation method thereof. Background technique [0002] Hot stamping is a special printing process that does not use ink. The so-called hot stamping refers to the process of hot stamping the electrochemical aluminum foil onto the surface of the substrate under a certain temperature and pressure, and it has many applications in packaging anti-counterfeiting. The graphics and text of anodized aluminum hot stamping can be combined with holographic imaging technology to show a strong metallic luster, bright and dazzling, and never fade. At the same time, due to the excellent physical and chemical properties of anodized aluminum, it plays a role in protecting printed products. Therefore, the hot stamping process is widely used in high-end and exquisite packaging trademarks, wall calendars and book covers and ...

AI Technical Summary

Problems solved by technology

If the temperature is too high and the melting is excessive, the anodized aluminum around the hot stamping image will also melt and fall off to produce a paste plate. At the same time, the high temperature will also cause chemical changes in the anodized aluminum dyed resin and the aluminum layer, and the brightness of the hot stamping product will decrease and lose its metallic luster. It may even cause fog spots or blisters on the imprint; but if the temperature is too low and the melting is insufficient, it will also cause the hot stamping to fail or not firm, the imprint is not firm, easy to fall off, or the pen is missing and broken, and the imprint is blooming. Especially when hot stamping aluminum foil with microstructure holographic image, because the information layer of holographic image is extremely precise, the original image of aluminum foil cannot be completely presented if there is a slight error

At the same time, the hot stamping film in the prior art cannot withstand high temperature, aging resistance, ultraviolet rays and other defects, which limits the application field of holographic anti-counterfeiting hot stamping film
