Abstract

The invention discloses a release-free laser electrochemical aluminum hot-stamping foil imaging layer coating and a preparation method thereof, and mainly solves the technical problems of harsh production field environment requirement of the conventional laser electrochemical aluminum hot-stamping foil imaging layer coating in a coating process, short service life of the coating, complex production process flow and the like. The invention adopts the technical scheme that the electrochemical aluminum hot-stamping foil imaging layer coating is prepared from the following raw materials in part by weight: 5 to 10 parts of polyurethane resin, 3 to 8 parts of nitrocellulose, 5 to 15 parts of polyacrylate resin, 1 to 8 parts of dehydrated malic acid resin, 0 to 10 parts of polyester resin, 0.1 to 5 parts of auxiliary agent and 50 to 85 parts of solvent. The coating can be directly coated on a PET carrier film, and the PET carrier film is prepared into a laser electrochemical aluminum hot-stamping foil product by laser die pressing, vacuum aluminizing, gum coating, slitting and rewinding; and the coating has no over harsh requirements for relative humidity of a production field and the like in the coating process, and the coating product has the properties of long service life and the like.

Description

technical field [0001] The invention relates to a laser anodized aluminum hot stamping foil imaging layer coating used in the production process of laser anodized aluminum hot stamping foil products for printing and packaging decoration materials and a preparation method thereof. Background technique [0002] At present, with the development of modern science and technology and the improvement of packaging and decoration grades, laser anodized aluminum hot stamping foil is based on the production technology of ordinary anodized aluminum hot stamping foil, combined with laser technology, laser molding technology, chemical raw material industry and chemical industry. High-grade packaging and decoration materials developed by the development of formula technology. Since the advent of laser anodized aluminum hot stamping foil, because of its bright and brilliant laser laser pattern, compared with the monotonous metallic luster of ordinary anodized aluminum hot stamping foil, it ...
