一种彩色透明防伪水印纸及其制作方法
摘要：
本发明涉及一种彩色透明防伪水印纸及其制备方法，该彩色透明防伪水印纸包括原纸，原纸中设置有彩色薄膜，彩色薄膜用量为纸张面积的0.1~10%。彩色薄膜为彩色PVA或明胶薄膜，包含0.01~0.3wt%的水溶性染料。将彩色薄膜按要求加工成需要的形状，通过定向释放装置，在纸浆中加入彩色薄膜，使之定向分布于纸张的某一部位，或使之均匀分布在纸张中。本发明方法制得的彩色透明防伪水印纸，具有很好的耐光、耐酸、耐碱、耐氧化剂、耐还原剂、耐有机溶剂、耐热等性能。因此，该材料能够很好的适用于证券、票据、钞票纸等防伪，加密技术领域。
摘要（英）：

The invention relates to colorized transparent anti-counterfeit watermark paper and a manufacturing method thereof. The colorized transparent anti-counterfeit watermark paper comprises body paper; a colorized thin film is arranged in the body paper; the using amount of the colorized thin film is 0.1 to 10 percent of the area of the paper; and the colorized thin film is colorized polyvinyl acetate (PVA) or a gelatin thin film, and comprises 0.01 to 0.3weight percent of water-soluble dye. The colorized thin film is processed into a desired shape as required; the colorized thin film is added into paper pulp through an orientated releasing device so that the colorized thin film is directionally distributed on a certain part of the paper or uniformly distributed in the paper. The colorized transparent anti-counterfeit watermark paper manufactured by the method has high light resistance, acid resistance, alkali resistance, oxidant resistance, reductant resistance, organic solvent resistance, heat resistance and the like, so the material can be well applicable to anti-counterfeit and encrypting technical field of securities, tickets, currency paper and the like.
