Hot stamping foil for irregular surface hot stamping

Abstract

The invention provides a hot stamping foil for irregular surface hot stamping. The hot stamping foil for the irregular surface hot stamping mainly solves the technical problems that hot stamping graphic cracking, graphic defects and poor hot stamping adhesion are prone to occurring during hot stamping of an existing hot stamping foil on all kinds of irregular surfaces. According to the technical scheme, a stripping layer coating is prepared by mixing raw materials including thermoplastic modified polyurethane, high edge-cutting acrylate, polyethylene wax and a mixed solvent; a transparent protective coating is prepared by mixing raw materials including a modified polyamide resin, ethyl hydroxyethyl cellulose and ethyl acetate; a coloring material is prepared by mixing rosin-modified acrylate, a short oily alkyd resin, cellulose acetate, a dye and a mixed solvent; an aluminum-layer protective layer coating is prepared by mixing a urea-formaldehyde resin, a novolac epoxy resin and butylacetate; a hot melt adhesive material is prepared by mixing low softening point thermoplastic acrylate, a coumarone-indene resin, an EVA resin of Tg50 DEG C, a rosin-modified alkyl phenolic resin, nano silica powder and a mixed solvent; and the hot stamping foil for the irregular surface hot stamping is obtained after sequential coating of the stripping layer coating, coating of the transparent protective coating, coating of the coloring material, vacuum aluminum plating, coating of the aluminum-layer protective layer coating and coating of the hot melt adhesive material. The hot stamping foilfor the irregular surface hot stamping has the characteristics that the irregular surface hot stamping is full, clear and has good adhesion.

Description

technical field [0001] The invention relates to a hot stamping foil for irregular surface hot stamping, which belongs to the technical field of coating printing. Background technique [0002] As a heat transfer packaging printing material, hot stamping foil is widely used because of its convenient use and exquisite hot stamping graphics. However, due to the limitation of production process and technology, conventional hot stamping foil can During hot stamping, a series of quality problems such as cracks in hot stamping graphics, incomplete graphics and poor adhesion of hot stamping are prone to occur, which affect quality and production efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide a hot stamping foil for irregular surface hot stamping that is plump, clear and has good adhesion. [0004] In order to achieve the above object, the technical solution adopted in the present inv...
