Abstract

The present invention discloses a UV photoluminescence ink, and belongs to the field of printing ink preparation. The UV photoluminescence ink is characterized in that modified ZnS:Cu is adopted as a luminescence material, a mixture of an epoxy acrylic acid resin and a polyester acrylate resin is adopted as a prepolymer, a mixture of trimethylolpropane triacrylate and tripropylene glycol diacrylate is adopted as a diluted monomer, a photoinitiator, an accelerator, an antifoaming agent and the like are matched, and uniform mixing is performed to obtain the finished product. The UV photoluminescence ink can be widely applicable for printing on securities, tax receipts, invoices, credit cards and other valuable bills.

Description

technical field [0001] The invention relates to a printing UV ink, that is, a UV photoluminescent ink used in the fields of commodity outer packaging, securities, tax invoices, invoices, credit cards and the like. Background technique [0002] Photoluminescent anti-counterfeiting ink has the characteristics of good concealment, bright colors, low cost and convenient implementation of anti-counterfeiting technology, and shows great application potential in the fields of securities, tax stamps, invoices, credit cards and other valuable notes. In recent years, a variety of photoluminescent anti-counterfeiting inks have been developed at home and abroad. For example, Chinese patent CN1544545A discloses a long afterglow luminous ink, Chinese patent CN1313364A discloses a luminous ink paint, Chinese patent CN1143659A discloses a universal color luminous ink, and Chinese patent CN1465631A discloses a non-emissive environmental protection energy storage Luminescent ink, Chinese pat...
