Embodiment Construction

[0023] The present invention is described in detail below in conjunction with embodiment.

[0024] A method for making a color-changing anodized aluminum self-adhesive anti-counterfeiting sticker of the present invention comprises the following steps:

[0025] (1) Superimpose the color-changing layer on the base layer, also known as the coloring layer: mix the binder containing the photosensitive material evenly, process it into a viscous paint, apply it evenly on the surface of the base film by anilox roller printing, and pass through five stages It is baked and dried in a type oven to increase the brightness and fullness of the product, and the color will be reversed under ultraviolet light and sunlight. The temperature sequence of the five-stage oven is 110°C-120°C-130°C-140°C-150°C, the pressure is 20pa, and the speed is 120m / min.

[0026] In this step, the miscibility of the photosensitive material and the binder and the viscosity of the solution should be fully consider...

Abstract

The invention relates to a discoloring anodized-aluminum adhesive sticker anti-counterfeiting paste manufacture method. A discoloring layer is overlapped on a plastic polyester film base layer. Connecting materials containing photosensitive materials are evenly mixed and processed to form a sticky coating, the sticky coating is evenly printed and coated on the surface of the film base layer through an anilox roller and baked and dried through a five-section type drying oven so as to improve the brightness and plumpness of products, and color inversion occurs under the irradiation of ultraviolet light and sunlight. A holographic anti-counterfeiting mould pressing layer is overlapped on the discoloring layer. A laser-printing information layer passes through a roller wrapped with laser engraving laser printing plate and forms invisible laser printing patterns and information serving as anti-counterfeiting graphics and text information at the 150 DEG C surface temperature and under the 30pa pressure. A printing layer is overlapped. A vacuum aluminium plating layer is overlapped on the printing layer. A gum application layer is overlapped. Finally, slitting and rewinding are performed. A discoloring anodized-aluminum adhesive sticker anti-counterfeiting paste manufactured by means of the method has the original characteristics of high gloss and high brightness and the discoloring characteristic, has an anti-counterfeiting function and is not easily counterfeited.

Description

technical field [0001] The invention relates to self-adhesive stickers, in particular to a method for making color-changeable anodized aluminum self-adhesive anti-counterfeiting stickers. Background technique [0002] At present, the more common anodized aluminum self-adhesive anti-counterfeiting stickers only have anti-counterfeiting text and patterns on the surface, and the color is relatively single, and they do not have the color-changing function. [0003] In view of this, seeking a kind of color-changing anodized aluminum self-adhesive anti-counterfeiting sticker and its manufacturing method has become the goal pursued by those skilled in the art. Contents of the invention [0004] The task of the present invention is to provide a method for making color-changing anodized aluminum self-adhesive anti-counterfeiting stickers, which solves the problems in the above-mentioned prior art, and has a color-changing function after being made. And the pattern will produce a c...
