Problems solved by technology

Most of the anodized aluminum hot stamping foils on the market today are only suitable for the hot stamping process. If they are directly applied to the cold stamping process, there will be a problem of high peeling force, which will slow down the hot stamping speed; When it is used, the color is relatively dull, and the overall thickness of the aluminum plating layer is consistent, resulting in poor adhesion, easy fall off, and short service life when the edge is embossed.
[0005] Patent CN109515053A discloses a preparation method of anodized aluminum foil for cold stamping technology, but its technology can no longer meet the higher requirements of cold stamping technology at the present stage, such as large solid, thin lines, high-speed ironing, non-flying gold, etc.

Abstract

The invention provides alumite hot stamping foil suitable for an offset printing and cold stamping technology and a preparation method thereof. The alumite hot stamping foil comprises a sheet base layer, an isolating layer, a dyeing layer, a fluorescent layer, an aluminized base layer and a protective layer. The dyeing layer is prepared from the following components including, by weight, 15 to 20.5 percent of organic silicon modified acrylic resin, 30.2 to 35 percent of thermoplastic methacrylic resin, 25 to 27.5 percent of butanone, 15 to 20 percent of butyl ester, 2 to 2.5 percent of toner, 0.5 to 0.8 percent of an active agent and 0.7 to 1.3 percent of a modifier. The resin of the dyeing layer of the alumite hot stamping foil is composed of the organic silicon modified acrylic resin and the thermoplastic methacrylic resin, the active agent and the modifier are added at the same time, and therefore the film breaking force of the dyeing layer is reduced, and the prepared alumite hot stamping foil has the advantages of being small in stripping force and good in transferability; and meanwhile, the preparation cost of the alumite hot stamping foil is considered, the hot stamping foil can be suitable for the offset printing and cold stamping technology, pollution to the environment in the metal printing plate manufacturing process is avoided, and the cold stamping speed is high.
