Optically-variable ink for screen printing

The invention provides an optically-variable ink for screen printing, which is prepared from the following components by weight: 5-20 parts of magnetic layered optically-variable pigment, 5-20 parts of magnetic liquid crystal pigment, 25-60 parts of ultraviolet-light cured resin, 0-40 parts of organic solvent, 1-10 parts of photoinitiator, 0-3 parts of a leveling agent and 0-3 parts of an antifoaming agent. The optically-variable ink for screen printing contains the magnetic optically-variable pigment, can realize the rolling type optically-variable dynamic characteristic of the printed product on the printing equipment with a magnetic positioning device, is visually recognizable, has an obvious optically-variable effect under the polarizer and has the hidden two-wire anti-counterfeiting characteristic. Therefore, the optically-variable ink for screen printing is the one-wire and two-wire optical anti-counterfeiting (optically-variable and polarized) magnetic positioning anti-counterfeiting ink and can achieve the rolling type optically-variable effect and the circularly-polarized optically-variable properties on the magnetic positioning screen printing equipment.
