Problems solved by technology

[0002] At present, the color of the traditional bronzing foil is fixed after bronzing, and it will fade naturally after a long time; if it needs to be anti-counterfeiting, it will not have the anti-counterfeiting function, and it is easy to be counterfeited
Therefore, the existing bronzing foil does not have anti-counterfeiting function

Embodiment Construction

[0020] The present invention is described in detail below in conjunction with embodiment.

[0021] A method for manufacturing a luminescent anodized aluminum hot stamping foil of the present invention comprises the following steps:

[0022] (1) With plastic polyester film as the base layer, a release layer is superimposed on the base layer, also called peeling layer: After dissolving the high-gloss and transparent synthetic solid wax with a solvent, it is evenly coated on the polyester film by anilox roller coating On the film, and baked and dried in a five-stage oven, so that all the coatings can be separated from the polyester film to achieve the effect of transfer. The temperature sequence of the five-stage oven is 100°C-110°C-120°C-130°C-120°C, the pressure is 20pa, and the speed is 150m / min.

[0023] (2) Superimpose the photosensitive layer on the release layer, also known as the color-changing layer: make a viscous coating from the binder containing the photosensitive m...

Abstract

The invention relates to a production method of a luminous alumite hot stamping foil. The production method comprises the following steps of: dissolving high-brightness and transparent synthetic solid wax by a solvent, evenly coating onto a polyester thin film by an anilox roller, and drying in a baking way by a five-section type oven; preparing a photosensitive material-containing connecting material into adhesive coating material, evenly coating on the surface of a release layer by printing and coating by the anilox roller, drying in a baking way by a five-section type oven so as to increase the brightness of a product, absorbing the energy of the visible light by a coating layer so as to stimulate the color of a substance to be changed, changing the original light color to be colorful under the irradiation of the sunshine or the ultraviolet light, and restoring the light-colored surface after a light source is removed; overlapping a vacuum aluminum-plated layer on a photosensitive layer; preparing soft-hard resin adding accessory ingredient and powder padding, and thermally printing on the surface of the vacuum aluminum-plated layer; and finally, slitting and rewinding. The luminous alumite hot stamping foil produced by the method provided by the invention replaces common dye with photoactive substance, so that after the foil is used, not only can the original color be kept, but also the color can be changed after the foil is irradiated by the light source, and therefore, the foil has an anti-fake function.

Description

technical field [0001] The invention relates to hot stamping foil technology, in particular to a method for manufacturing a luminescent anodized aluminum hot stamping foil. Background technique [0002] At present, the color of the traditional hot stamping foil is fixed after hot stamping, and it will fade naturally after a long time; 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 luminous 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 luminescent anodized hot stamping foil, which solves the problems in the prior art above. After hot stamping, when there is a light source, the color will change. Display red, yellow, green,...
