Pigment sheet and manufacturing method thereof

Abstract

The invention discloses a manufacturing method for a pigment sheet. The method comprises the following steps of: providing a substrate layer, wherein a concave image-text area and convex defect areas formed on the periphery of the convex image-text area are formed on the substrate layer; forming a pigment film on the substrate layer to form a first convex image-text area which corresponds to the concave image-text area and a first concave defect area which corresponds to the convex defect area on the paint sheet; separating the pigment film from the substrate layer; and smashing the pigment film to fracture the pigment film along the first concave defect area and form a pre-shaped pigment sheet defined by the first convex image-text area. Moreover, the invention further discloses a pigment sheet of preset shape. Due to the adoption of the technical scheme, the pigment sheet of a preset shape can be formed at relatively high production efficiency, high integrality of information carried by the pigment sheet and a good representation effect, and can be applied to ink or other carriers for counterfeiting and decorating.

Description

technical field [0001] The invention relates to the technical field of pigments, in particular to a pigment flake with a preset shape and a manufacturing method thereof. Background technique [0002] In the prior art, microscopically fine metal flakes carrying information are often introduced into the ink in the form of marks. The manufacturing process of the metal fine flakes is generally to use a UV excimer laser to ablate the thin metal surface to form embossed information. The thin metal sheet with convex information is made into fine flakes by ball milling process, and the embossed fine flakes are used as information carriers to play the role of anti-counterfeiting or device. [0003] In the above-mentioned manufacturing process, the production process of UV excimer laser is complicated, the production efficiency is low, and it is difficult to mass-produce, while the embossed information produced by the micro-embossing method is poor in display effect, and when crushed...

AI Technical Summary

Problems solved by technology

[0003] In the above-mentioned manufacturing process, the production process of UV excimer laser is complicated, the production efficiency is low, and it is difficult to mass-produce, while the embossed information produced by the micro-embossing method is poor in display effect, and when crushed by ball milling, the fine metal flakes are Collision random crushing, easy to destroy the embossed information carried by the metal fine flakes. In addition, the shape of the pigment flakes is irregular, and it is difficult to distinguish them from other pigment flakes when mixed with other pigment flakes. Therefore, the anti-counterfeiting and decorative effects are greatly reduced.
