Abstract

The invention discloses an ultraviolet light-curable seamless holographic laser transfer varnish. The ultraviolet light-curable seamless holographic laser transfer varnish comprises the following components calculated by weight percentage: 30%-40% polyester acrylate Resin; 5%‑15% ethoxylated trimethylolpropane triacrylate; 35%‑45% ethoxylated 1,6‑hexanediol diacrylate; 8%‑12% tertiary amine co-initiator; 0.1% ‑0.3% 819 photoinitiator; 0.2%‑0.4% TPO photoinitiator; 2.5%‑3.5% macromolecular photoinitiator; 0.05~0.1 inhibitor; 0.2%‑0.4% leveling agent; foaming agent. The prepared UV-cured seamless holographic laser transfer varnish has no solvent and no toxic gas emission when used, and is environmentally friendly and pollution-free. After curing, the laser pattern and BOPP base film are easy to peel off, leaving no residue and no smell. The laser pattern is on the printed matter The pattern of surface curing molding is clear, and the laser effect is strong, which can meet the requirements of laser decoration effect and laser anti-counterfeiting effect.

Description

technical field [0001] The invention relates to the technical field of printing inks, in particular, the invention relates to a UV-curable seamless holographic laser transfer varnish and a preparation method thereof. Background technique [0002] The principle of laser pattern imprinting transfer technology is: apply UV varnish on the surface of the printed matter, combine with the prefabricated laser pattern transfer film through the pressure of the laser pattern imprinting transfer machine, and transfer the laser pattern after the UV varnish is cured and finalized. The film is peeled off from the product. In this way, it is convenient to form a shiny and bright pattern corresponding to the laser pattern transfer film when the UV varnish is coated on the surface of the product. [0003] The laser pattern transfer film is covered with regular patterns, which are composed of countless tiny prism-like cells. When the printed matter coated with UV varnish is combined with the...
