[0003] The composite paper with anti-counterfeiting patch with application number "CN201520714915.9" is a unique anti-counterfeiting patch layer made by applying a special water-based coating liquid on the base paper, so it can be combined with paper fibers, will not decompose in the pulp, and can maintain its inherent shape. This technology cannot be imitated at all; the composite paper containing the anti-counterfeiting patch is very easy to identify, and does not require complex equipment inspection, and can be distinguished by visual observation and simple instruments. However, in the above scheme, moisture can easily corrode the base paper layer in humid weather, and the water-based coating can be easily worn, affecting the anti-counterfeiting effect.
