Abstract

The invention relates to the technical field of cold ironing membranes and in particular relates to a cold ironing membrane for a digital printing machine and a preparation process of the cold ironingmembrane. The cold ironing membrane for the digital printing machine comprises a PET (polyethylene terephthalate) gold ironing substrate, a separation layer, a mold pressing laser information layer and a UV (ultraviolet) medium layer which are arranged in sequence, wherein the separation layer comprises aqueous acrylic acid, water and ethanol; the mold pressing laser information layer comprises an acrylate polymer, butanone, butyl acetate and an aid; and the UV medium layer comprises polymethacrylate, butyl acetate, ethyl acetate, an aid and silica powder. Due to properties of thermoplasticity and thermal setting of the acrylate copolymer, the mold pressing laser information layer is large in imitation difficulty, bright in lens and empaistic effect and good in three-dimensional property;in addition, the membrane can be applied to two process of first peeling and setting later and first setting and peeling later, is wide in application range and in addition has the advantages of being good in anti-fake performance and is not easy imitate; and the preparation process has the characteristics of being simple in process, low in production cost and applicable to large-scale production.

Description

technical field [0001] The invention relates to the technical field of cold-foil film, in particular to a cold-foil film for a digital printing machine and a preparation process thereof. Background technique [0002] With the development of the market and the improvement of consumer concepts, the laser effect of ordinary digital printing cold foil technology is difficult to meet the needs of high-end products. The development of multifunctional digital printing cold foil technology has greatly improved the three-dimensional effect and metal texture. than ordinary lasers. As a new type of anti-counterfeiting technology, digital cold stamping technology will be more and more widely used in the label and packaging industry. [0003] In addition, due to the limitation of the formulation process of the existing digital cold-foil film formula, in the choice of peeling and then curing or first curing and peeling, it may be necessary to choose two formulas due to different customer...
