A kind of anti-counterfeiting paper and its manufacturing method

Abstract

A security paper comprises at least two layers of independently molded paper pages. A fiber textile belt is arranged between the two paper pages and provided with a security element; the fiber textile belt comprises a silk screen layer woven from a hot melting material with melting point at 50-100 DEG C; the fiber textile belt forms a white watermark on the paper page; and the security element forms a black watermark on the paper page. The invention solves technical problems in the prior art that a positioning security component addition method is not suitable for a molded security element and that security element addition using a water-soluble material as a carrier requires a long processing time and results in poor paper effect. The security paper provided by the invention is particularly suitable for the production of valuable documents and security document.
