Embodiment Construction

[0032] Below in conjunction with specific embodiment, content of the present invention is described in further detail:

[0033] refer to figure 1 , an optically variable color anodized aluminum hot stamping foil, comprising a biaxially stretched polyester film 1, a release layer 2 is formed on the biaxially stretched polyester film; a colored layer 3 is formed on the described release layer; the colored layer On the layer is an aluminum plating layer 4; on the aluminum plating layer is an adhesive layer 5; when the color layer is colored, an optical variable pigment is used as a colorant.

[0034] A production method of an optically variable color anodized aluminum hot stamping foil, comprising the following steps:

[0035] (1) Use a 120-300 mesh gravure anilox roll to coat the wax emulsion with water as the dispersion solvent on the surface of the biaxially oriented polyester film, dry and roll to form a release layer;

[0036] (2) Apply color layer paint on the surface of ...

Abstract

The invention discloses an optical variability color hot stamping foil. The optical variability color hot stamping foil comprises a two-way stretching polyester film, and a release layer is arranged on the two-way stretching polyester film; a color layer is arranged on the release layer; an aluminum coating layer is arranged on the color layer; a rubber layer is arranged on the aluminum coating layer; and an optical variability pigment is used as a coloring agent when the color layer is colored. The invention further discloses a production method of the optical variability color hot stamping foil. The optical variability color hot stamping foil and the production method have the beneficial effects that the optical variability pigment is used as the coloring agent when the color layer is colored, different colors are displayed when naked eyes observe the foil from different angles, and the unique and novel aesthetic perception is achieved; and the color sensation cannot be copied through the methods of copying, scanning, camera shooting and the like, and the high anti-fake performance is achieved.

Description

technical field [0001] The invention relates to the technical field of hot stamping foil, in particular to an optically variable color anodized aluminum hot stamping foil and a production method thereof. Background technique [0002] Anodized aluminum hot stamping foil is a film-like material for thermal transfer made by coating several layers of coatings with different functions on the surface of plastic films and vacuum-evaporating an aluminum layer. It is widely used in paper, plastics, etc. After printing, it is processed to obtain text patterns or color blocks with metallic luster. [0003] traditional craft: [0004] 1. Release layer [0005] The surface of the biaxially oriented polyester film (BOPET) is coated with OP wax with butanone as the main solvent, and the organic solvent is dried and discharged in an oven. [0006] 2. Color layer [0007] Coat the color layer coating on the surface of the release layer. The color material contained in the color layer coa...
