The invention relates to the technical field of printing and particularly relates to a hot
gold foil. The hot
gold foil comprises a base film layer, a release layer on the base film layer, a colour layer on the release layer and an
aluminium coated layer on the colour layer, wherein an ink layer is arranged at the bottom of the
aluminium coated layer, during
hot stamping, firstly, a worker can lay one side, provided with the ink layer, of the hot
gold foil onto the surface of a to-be-printed object, through heating and pressing of a gold
stamping machine and a
hot stamping template, the
metal foil of the hot gold foil is printed on the surface of the to-be-printed object, during
hot stamping, the ink layer provided by the invention is positioned in a high temperature environment with the temperature of more than 100 DEG C, at the moment, the stickiness of the ink layer is increased after melting by heating, and printing onto the to-be-printed object is achieved while the
aluminium coated layer and the base film layer are peeled off. With
pressure release, the ink layer is quickly cooled and solidified, and the aluminium coated layer is firmly adhered onto the to-be-printed object, so that the
metal foil of the hot gold foil is firmly adhered onto the to-be-printed object. Therefore, due to the use of the hot gold foil for gold
stamping, the gold
stamping process and steps are simplified, the production efficiency is improved, and the product cost of manufacturers is lowered.
