Hot stamping foil applied to overlapping hot stamping on gold stamping layer and preparation method of hot stamping foil

Abstract

The invention discloses an anodized aluminum hot stamping foil applied to overlapping hot stamping on a bronzing layer and a preparation method thereof. The existing anodized aluminum hot stamping foil may have transfer incompleteness, missing hot stamping, pasting, and dropout during overlapping hot stamping. There are disadvantages such as powder and unclear edges of the hot stamping layer. The hot stamping foil of the present invention is composed of a base film layer, a release layer, a colored layer, a vacuum aluminized layer and an adhesive layer, and the adhesive layer is prepared from the following raw materials in parts by weight: vinyl chloride-vinyl acetate resin 1-6 1-10 parts of polyvinyl alcohol, 1-10 parts of acrylate, 1-5 parts of nitrocellulose, 1-5 parts of fumed silica, 20-70 parts of ethyl acetate, 10-50 parts of ethanol, propyl acetate 1-5 parts of ester. The present invention is applied to anodized aluminum hot stamping foil for overlapping hot stamping on the hot stamping layer, which has good hot stamping and trimming properties, complete transfer of overlapping hot stamping layers, smooth edges without burrs and firm adhesion, no flying gold, peeling off Powder and other phenomena, the hot stamping effect has a strong three-dimensional effect, and the anti-counterfeiting performance is more prominent.

Description

technical field [0001] The present invention relates to a printing plate or foil, and the materials used therefor, more specifically to an anodized aluminum hot stamping foil applied to hot stamping on a hot stamping layer and a preparation method thereof. Background technique [0002] Anodized aluminum hot stamping foil is a new type of packaging material for vacuum aluminum plating. The pre-engraved patterns, lines and fonts on the hot stamping plate are transferred to the surface of the substrate through the principle of hot pressing, so that it has bright color, strong metallic feeling, visual It has been widely used in hot stamping and decoration on the surface of paper products, plastic products, leather products, wood products and so on. [0003] Anodized aluminum hot stamping foil is composed of base film layer, release layer, coloring layer, vacuum aluminized layer and adhesive layer. Its preparation method includes coating release layer and coloring layer on the...
