Abstract

The invention discloses UV (ultraviolet) cold stamping glue. The UV cold stamping glue contains urethane acrylate oligomer, polyester acrylate oligomer, epoxy acrylate oligomer, phosphate adhesion promoters, acrylate monomer and auxiliaries, wherein the glue further contains ester-soluble vinyl chloride-vinyl acetate resin and aryl (methyl) semi-acrylate. The UV cold stamping glue disclosed by the invention has excellent adhesion on a vacuum coating, especially an aluminum-coated layer. The UV cold stamping glue can be used for solving the technical state that a connecting layer is needed to be additionally arranged outside a vacuum coating for an existing cold stamping film, thereby simplifying the production process of the cold stamping film, lowering the manufacturing cost of the cod stamping film and reducing the emission of VOC (volatile organic compounds).

Description

technical field [0001] The invention relates to a glue, in particular to a UV cold stamping glue. Background technique [0002] For a long time, hot stamping has occupied the main market share of holographic anti-counterfeiting, but due to its disadvantages such as low processing speed, harsh hot stamping conditions and high processing costs of hot stamping plates, the market promotion of hot stamping has been restricted to a certain extent. Compared with hot stamping, cold stamping technology has many advantages, such as fast stamping speed, the fastest speed can reach 60~120m / min, while the general round hot stamping speed is only 20~30m / min; hot stamping The base material has a wide range of applications, and can be cold-stamped on heat-sensitive paper and some film materials; the cost is saved by using a general flexographic plate instead of an expensive metal plate cylinder; no heating cylinder is used, which saves energy and reduces consumption; No metal plate cylinde...
