Abstract

The invention relates to the field of printing technology and discloses an environment-friendly optically variable screen printing ink. The environment-friendly optically variable screen printing inkis characterized by including, by weight percentage, 25-40% of UV (ultraviolet) polyester acrylate, 15-30% of environment-friendly diluting monomers, 25-40% of high-wear-resistance UV polyurethane modified resin, 1-2% of defoamer, 1-3% of BYK flatting agent, 10-15% of slice optical variable paint, 3-8% of directional agent and 1-5% of wear-resisting additives. Compared with the prior art, the environment-friendly optically variable screen printing ink is recognizable in natural light, high in anti-forgery performance, variable in color as angle changes and significant in optically varied colordifference.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to an environmentally friendly optical color-changing ink for silk screen printing. Background technique [0002] 3D dynamic anti-counterfeiting label is a kind of product that combines microlens array with array image or text. The dynamic effect is obvious and intuitive to the naked eye. It is one of the high-end technologies that will replace the current mainstream anti-counterfeiting technology in the future. However, the current 3D dynamic anti-counterfeiting labels are mainly based on light-sensitive color-changing products. The color-changing conditions are single, the anti-counterfeiting effect is poor, and the light-changing color difference is not obvious, and it is easy to be copied. Contents of the invention [0003] Purpose of the invention: Aiming at the problems existing in the prior art, the present invention provides an environmentally friendly optical color-chang...
