Problems solved by technology

Using soft resin as the holographic color layer and transferring the pattern on the UV curing layer can achieve a holographic depth of 5 μm, but the soft resin has poor wear resistance. After hot stamping, the soft resin holographic color layer is exposed on the surface of the ironing object, which is easy to wear Holographic effect decreased
If the holographic color layer is directly made into a reaction curing type to increase wear resistance, the bonding force between the holographic color layer and the UV curing layer will be tight, and it will not be easy to separate during hot stamping, resulting in incomplete hot stamping
And because the structure of the holographic color layer is single, it cannot achieve the luster effect like jade porcelain

The holographic hot stamping film comprises a UV curing layer, a holographic glaze color layer and a jade porcelain color layer which are stacked in sequence; the UV curing layer comprises a first surface and a second surface, and a holographic micro-groove structure is arranged on the second surface; the holographic glaze color layer is formed on the second surface of the UV curing layer, the holographic glaze color layer comprises a third surface and a fourth surface, and holographic micro-groove structures are copied on the third surface and the fourth surface; and the jade porcelain color layer is formed on the fourth surface of the holographic glaze color layer, the jade porcelain color layer comprises a fifth surface and a sixth surface, the fifth surface is attached to the holographic glaze color layer, and a holographic micro-groove structure is also copied on the fifth surface. According to the holographic hot stamping film, the anti-reflection and brightening holographic glaze color layer is added between the UV curing layer and a holographic color layer, a material formula of the holographic color layer is improved, the new reaction curing type jade porcelain color layer is formed, the jade porcelain-like glossy and non-transparent holographic film is realized, and the wear resistance of a holographic pattern is good.

Description

technical field [0001] The present application relates to the field of anti-counterfeiting technology, in particular to a holographic hot stamping film with the effect of glazed jade porcelain and a preparation method thereof. Background technique [0002] The traditional holographic hot stamping film is composed of a substrate layer, a release layer, a holographic color layer, a coating layer, and an adhesive layer. After the holographic hot stamping film is hot stamped, there will be residual release wax on the surface of the hot stamping pattern, which will cause the holographic pattern to be foggy, and because The concave-convex structure of the holographic pattern is on the side facing the adhesive layer, so the holographic pattern must be separated from the adhesive layer by a coating, otherwise the adhesive layer will be directly filled into the concave-convex structure of the holographic pattern and the holographic effect will be destroyed, and the opaque holographic ...
