Light solidified rare earth red flruorescence anti-forge printing ink and preparation process thereof

Abstract

The invention is a photocurable rare-earth red fluorescent anti-falsification printing ink and its preparing method, using 'in situ process' wet-chemical technique, adopting 'in situ process' to synthesize rare-earth complex material in photocurable resin substrate, according to the components in the photocurable resin, synthesizing Eu-TTA-AA-Phen rare-earth complex in diphenol A epoxy acrylic ester substrate, where the new generated complex uniformly disperses in the resin substrate so as to make the rare-earth complex obtain high uniform dispersivity in the photocurable substrate, and the complex is fixed in the substrate network, under the protection of the substrate material, not only preventing the formation of congeries particles but also the automatic congregation of the complex, preventing the formation of congeries, thus obtaining the optical-transparency and high-lighting efficiency high-molecular material of photocurable fluorescent anti-falsification printing ink.

Description

technical field

[0001] The invention relates to a printing ink (international classification number CO9D11 / 10) mainly based on artificial resin, in particular to a photocurable rare earth red fluorescent anti-counterfeiting ink and a preparation method thereof. Background technique

[0002] The potential application of rare earth fluorescent complexes in laser materials, photoluminescent materials, electroluminescent materials, etc. has aroused great interest of researchers due to their excellent luminescent properties. It plays an important role in the transformation process. The polymer materials containing luminescent rare earth complexes have both the high luminous intensity and high color purity of rare earth materials and the rich raw materials, convenient synthesis, easy molding and processing, and impact resistance of polymer materials. The rare earth polymer material is formed by bonding or doping rare earth ions into the polymer material. Among them, the doping of...
