How to used non-EU-banned insoluble azo dyes to prepare a new-type colour-display anti-counterfeiting paper(ACP) is investigated in this paper. The ACP will display red spots when it is wiped with alcohol. Through studying its mainly affecting facts ,including the dosage of Naphthol AS-BO ,dosage of Chromophore Red-B, the Chromophore's pH value and the drying temperature etc.,the best optimize technological conditions are obtained of insoluble azo dyes' color-displaying on the paper for the purpose of anti-counterfeiting. After the red spot are displayed in the paper,the chromatic aberration and physical properties of the paper are detected. The results showed that the paper made by adding Chromophore Red-B and Naphthol AS-BO had a very good anti-counterfeiting effect, while its physical properties had only changed a little.
