A kind of multifunctional cold transfer hot stamping film and its manufacturing process

Abstract

The invention provides a multifunctional cold transfer bronzing film and a manufacturing process thereof, and relates to the technical field of cold stamping films. The bronzing film includes a base material layer, a release coating applied on the base material layer, and a release coating The imaging coating on the imaging coating, the aluminum layer or the dielectric layer coated on the imaging coating, and the protective coating coated on the aluminum layer or the dielectric layer; wherein the coating of the release coating includes acrylic resin, polyurethane resin, isopropyl Alcohol, n-butanol, methanol; coatings for imaging coatings include chloroacetate resin, maleic acid, acrylic resin, epoxy resin, methyl ethyl ketone, ethylene glycol methyl ether; coatings for protective coatings include chloroacetate resin, malein acid, rosin resin, ethanol, n-butanol. The bronzing film of the invention is suitable for the transfer of metallic texture patterns on offset printing, flexographic printing and silk-screen cold stamping printing machines, and realizes multi-functionality. In addition, the hot stamping effect is good, and the yield, applicability and production efficiency of post-processing products are improved.

Description

technical field [0001] The invention relates to a multifunctional cold transfer hot stamping film and a manufacturing process thereof, belonging to the technical field of cold stamping films. Background technique [0002] Cold transfer (also known as cold hot stamping) refers to the method of transferring hot stamping foil to a substrate using a set of printing units as an adhesive coating unit. The cold stamping process needs to be divided into two steps. The first step is to transfer the special glue to the surface of the ironing object and make it firmly attached; the second step is to transfer the hot stamping paper to the surface of the ironing object through pressure. Transfer graphic information to a sticky, coated photosensitive layer. [0003] Compared with the traditional hot stamping technology, its advantage is that it can use ordinary flexographic plate, no need to make a metal plate, fast plate making, short cycle, low cost, fast online hot stamping, no need f...

AI Technical Summary

Problems solved by technology

[0005] 1. Cold transfer coatings and products produced are prone to defects such as edge chipping after transfer, broken wires and slow transfer, which will affect the post-processing yield and efficiency

[0006] 2. The coated high-viscosity adhesive has poor leveling property and uneven plates, causing diffuse reflection on the surface of cold stamping foil, affecting the color and gloss of stamping graphics, thereby reducing the aesthetics of the product

[0007] 3. The general cold-foil formula in the current market can only match one cold-foil printing method alone. Different customers have different processes and need to order cold-foil foil separately. It is difficult to achieve commercialization and market labeling, which restricts the scope of application of cold transfer film
