Abstract

The invention relates to a gradient color electrolytic aluminum hot stamping foil and a production method thereof and belongs to the field of printed packaging material production and processing. A product produced through a traditional process is single in color, and after the product is used in a hot stamping manner, only a single-color block image-text may be presented; when multi-color hot stamping is utilized, the accuracy of a hot stamping cover is relatively low, which may be found out easily by naked eyes, and products most are full colored at a time and thus very easy to copy in hue appearance. The gradient color electrolytic aluminum hot stamping foil has the following advantages that 1, a color layer is colored in a single linking gradient-two-color hanging net registration coating way, and colors are presented in such a manner of seamless transition from one single color to another color; 2, when a customer designs a hot stamping pattern, the customer does not need to design two-color overprinting, and seamless gradient two colors can be realized through single gold stamping; 3, a hanging net curve of a coating roller is adjusted to obtain different color transition curves, and the hue is extremely difficult to restore, thereby realizing a certain anti-counterfeit functional feature; and 4, during two-color overprinting, two hues are added by an any point to achieve 100% dry coating weight, and the two hues have consistent physical properties without affecting subsequent hot stamping use by customers.

Description

technical field

[0001] The invention relates to a gradually changing color anodized aluminum hot stamping foil and a production method thereof, belonging to the field of production and processing of printing and packaging materials. 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. The traditional process generally uses biaxially oriented polyester film (BOPET) to coat the OP wax with methyl ethyl ketone as the main solvent, and then passes through the oven, and the organic solvent is dried and discharged; then the color layer coating is applied on the surface of the release layer, and the color layer coating The roller is a 100~300-mesh no...
