Abstract

The invention is about a method of marking ink which is only used to defend fake. The composition of it is: lipidol or lipid, surface active agent, integration agent, water, buffering agent. Their mass percents are: 1,2-hexylene glycol: 5%-15%, butanol: 1-5%, DH-1: 5-10%, EDTA: 0.1-0.5%, MS-1: 0.1-1%, water: the rest. The process is: a. dissolving the colorant in water, b. put the correct percent of 1,2-hexylene glycol and butanol into the solvent, then dropping the MS-1 and EDTA solution when mixing the solvent for 30-50 min, c. put the rest precent of water into the printing ink box. The picture and word would be shown red fluorescence in the UV but blank in the usual light.
