Problems solved by technology

When performing gravure printing and screen printing, in addition to paying attention to its viscosity, binder, drying and other characteristics, it is also necessary to pay attention to the adjustment of its printing pressure, so that the printing pressure cannot be too large and affect the printing effect.

Abstract

The invention discloses ultraviolet fluorescent printing ink. The ultraviolet fluorescent printing ink consists of the following raw materials in parts by weight: 5 to 30 parts of fluorescent rare earth nanopaticles, 1 to 20 parts of epoxy resin, 5 to 10 parts of polyurethane, 10 to 35 parts of fluorescent pigment, 1 to 15 parts of flatting agent, 0.1 to 0.5 part of defoaming agent, 1 to 5 parts of opacifying agent, 0.1 to 5 parts of soya bean lecithin and 2 to 3 parts of ultraviolet light absorber, wherein the fluorescent pigment is organic ultraviolet fluorescent pigment with a macromolecule conjugated structure; and the opacifying agent is a mixture of zinc oxide, calcium carbonate and argil. The ultraviolet fluorescent printing ink has an obvious anti-counterfeit feature, is applicable to various printing modes and has high printing quality.

Description

technical field [0001] The invention relates to an ink composition, in particular to an ink composition containing fluorescent particles. Background technique [0002] Fluorescent ink is a fluorescent material added to ordinary ink, mainly used for anti-counterfeiting of printed products, suitable for all kinds of securities, bills, product packaging, trademarks, and decoration printing. The main component of fluorescent ink is fluorescent pigment. Fluorescent pigment is a functional luminous pigment. The difference from ordinary pigments is that when exposed to external light (including ultraviolet light), it can absorb a certain form of energy and excite photons, which will be emitted in the form of low visible light. The absorbed energy is released, resulting in fluorescence of different hues. Different colors of light combine to form extremely bright colors, and when the light stops shining, the luminescence phenomenon disappears, so it is called fluorescent pigment. F...
