Problems solved by technology

[0002] The existing anti-counterfeiting seal imprints all have their own unique anti-counterfeiting tracking marks, but when the seal imprint is stamped on the paper, anyone can see it with the naked eye, which is very obvious and does not have any concealed anti-counterfeiting effect; and The existing anti-counterfeiting seal imprints cannot establish a unique and non-destructive identification tracking mark; therefore, none of the current anti-counterfeiting seal imprints can achieve real anti-counterfeiting, and the authenticity is difficult to identify; in addition, the anti-counterfeiting of the existing online seal imprints can only be stamped The authenticity of the printed impression can be identified with the naked eye or by comparison. It is impossible to identify the authenticity of the seal imprint, and it cannot be identified from the printing oil.
[0003] To sum up, the anti-counterfeiting of the existing online seal imprint cannot be concealed, and it is difficult to distinguish the authenticity and authenticity of the online seal imprint, so it cannot achieve real anti-counterfeiting

Abstract

The invention relates to special ultraviolet fluorescent anti-counterfeit networked stamp ink, which is prepared from the following materials in percentage by weight: 5 to 50 percent of environment-friendly castor oil rein, 1 to 20 percent of ultraviolet fluorescent powder, 0.01 to 6 percent of environment-friendly dispersant, 0.01 to 6 percent of environment-friendly leveling agent, 0.01 to 6 percent of environment-friendly defoaming agent, 2 to 4 percent of environment-friendly wax, 1 to 30 percent of high-boiling point environment-friendly solvent and 1 to 20 percent of environment-friendlyfast red salt; the sum of the percentages by weight of all the materials is 100 percent. The special ultraviolet fluorescent anti-counterfeit networked stamp ink disclosed by the invention has an extremely high concealing property, a detector is adopted to identify the authenticity of a stamp from the color change angle of the ink when the authenticity of the stamp is identified, and thereby a more visual method is provided for stamp identification, so that the identification of stamp authenticity becomes more convenient and reliable.
