Electrochemical aluminum for stamping gold on ultraviolet (UV) glazing oil surface and preparation method thereof

Abstract

The embodiment of the invention provides electrochemical aluminum for stamping gold on an ultraviolet (UV) glazing oil surface. The electrochemical aluminum comprises a base film layer, a stripping layer, a colorable information layer, an aluminum coating and a bonding layer; the base film layer 1 is made of a polyethylene terephthalate film; the stripping layer is positioned on the base film layer and made of a fluorine-containing water-based wax material prepared by an emulsified paraffin method; the colorable information layer is positioned on the stripping layer and prepared from synthetic resin and at least two toner dyes; full series laser anti-counterfeiting information is positioned and die-pressed on the colorable information layer; and the bonding layer is positioned on the aluminum coating and prepared from acrylic mixed resin added with olefin surfactant. The embodiment of the invention also provides a preparation method for the electrochemical aluminum for stamping the gold on the UV glazing oil surface. According to the embodiment, an electrochemical aluminum god stamping material prepared from a special stripping agent and adhesive at a low temperature is excellent in performance and suitable for most printed materials of which the surfaces are provided with UV glazing oil.

Description

Technical field [0001] The invention relates to the technical field of printing, in particular to an electrochemical aluminum capable of bronzing on the surface of UV varnish and a preparation method thereof. Background technique [0002] Anodized aluminum bronzing is a very important post-press processing technology in packaging printing, mainly bronzing patterns, text, lines to highlight the product's ranking, trademark, tag, beautify the product, thereby improving the grade of the packaging product. The bronzing anodized aluminum with the anti-counterfeiting information layer is more difficult to forge due to the complicated production process, and can play an effective anti-counterfeiting effect. UV glazing oil is often used in the finishing of plastic or carton outer packaging, which plays a role of beauty and even anti-counterfeiting. The combination of bronzing anodized aluminum and UV varnish will greatly improve the quality and anti-counterfeiting effect of the product....

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide an optimized anodized aluminum product, which not only has a whole series of laser anti-counterfeiting products, but also aims at the problems that the bronzing does not go on and the bronzing is not firm when performing bronzing on various common UV varnish layers. effect, and can directly carry out hot stamping on various UV varnish layers, which has the same effect as hot stamping on other common substrates
