Manufacturing method of color-changing electric aluminum hot stamping foil

Abstract

The invention relates to a manufacturing method of a color-changing electric aluminum hot stamping foil. The method comprises the following steps of: dissolving a high-brightness and transparent synthesized solid wax by a solvent, then evenly coating the solution on a polyester film by an anilox roller, and baking and drying by a five-section type oven; preparing adhesive coating by using a connecting material containing a photosensitive material, evenly printing and coating the adhesive coating onto the surface of a release layer, and baking and drying by the five-section type oven to improve the brightness and the fullness of a product and enable the product to reflect the color which is different from that at the normal temperature along with the temperature change, or enable the color to be inversely changed under ultraviolet light or sunlight; forming an aluminum film layer; blending hard and soft resin additives and powder fillers, and performing hot stamping on the product on the surface of a vacuum aluminum plating layer; finally, slitting and rewinding. The color-changing electric aluminum hot stamping foil not only has the original characteristics of high gloss and high brightness, and the color of the hot stamping foil can be changed when the outside temperature changes, so that the product grade is improved, and the product has the anti-counterfeiting function due to a series of color change.

Description

technical field

[0001] The invention relates to hot stamping foil technology, in particular to a method for manufacturing a color-changing anodized aluminum hot stamping foil. Background technique

[0002] At present, after the traditional bronzing foil is bronzed, its color is fixed and the golden color is still maintained; if it needs to be anti-counterfeiting, it will not have the anti-counterfeiting function, and it is easy to be counterfeited. Therefore existing bronzing foil does not possess anti-counterfeiting function.

[0003] In view of this, seeking a color-changing hot stamping foil and its manufacturing method has become the pursuit goal of those skilled in the art. Contents of the invention

[0004] The task of the present invention is to provide a method for making color-variable anodized aluminum hot stamping foil, which solves the problems of the above-mentioned prior art. There will be a color change, from colored to colorless or from colorless to color...
