Abstract
Disclosed is a UV-curable transfer ink which can be cured by UV and used to emboss a precise and clear pattern on a substrate. It comprises 20-40% by weight of a UV-reactive ink, 20-40% by weight of an acrylic copolymer, 4-6% by weight of an ethylene vinyl acetate copolymer, 25-35% by weight of an organic solvent and 0.5-5% by weight of a bulking agent. A printing sheet is also provided, on which the transfer ink is printed in a predetermined pattern. An embossed pattern is obtained by applying the sheet to a substrate, exposing it to UV to cure the printed transfer ink, releasing the printing sheet to leave the cured transfer ink on the substrate, and etching the substrate.
