| 目的 研究不同造纸助留剂CPAM， APAM， 高取代度淀粉和变性淀粉对紫外光致变色防伪纸的物理性能和防伪性能的影响。方法 系统研究了4种常用造纸助留剂对光致变色材料在防伪纸中的留着量的影响， 评定防伪纸的物理性能和防伪性能， 从而确定了不同助留剂在浆料中的最佳用量。结果 光致变色防伪纸的抄造特性和防伪性能与纸料体系中所用助留剂的种类和性能密切相关。在一定的光致变色材料体系下， 不同助留剂的最佳加入量为变性淀粉的质量分数1.5％， CPAM的质量分数0.005%， APAM的质量分数0.015%， 高取代度淀粉的质量分数0.15%。结论 在浆料中加入助留剂后， 紫外光致变色材料在防伪纸中的留着量显著增加， 且加入助留剂的种类不同时， 其纸张的相对荧光强度值也不同， 从而保证了紫外光致变色纸张的防伪效果。 |

| To study the effects of adding different retention aid agents including CPAM, APAM, starch of high substitution degree and modified starch on the physical properties and anti-counterfeiting performance of ultraviolet photochromic anti-counterfeiting paper. Four kinds of commonly used retention aid agents were used to systematically study the dosage of photochromic material in anti-counterfeiting paper, and the physical properties and anti-counterfeiting performance of the anti-counterfeiting paper were evaluated, to determine the optimal dosages of different retention agents in the pulp. The physical and anti-counterfeiting performances of the photochromic anti-counterfeiting paper were closely related to the types and dosage of retention agent in the pulp system. In a certain photochromic material system, the optimal dosages of different retention agents were starch 1.5％， CPAM 0.005%， APAM 0.015%， starch of high substitution degree 0.15%. The retention of ultraviolet photochromic materials in anti-counterfeiting paper increased significantly after addition of retention agent in the slurry. Moreover, the types and dosage of the retention agent determined the relative intensity of fluorescence of the paper, and therefore ensured the anti-counterfeiting effect of ultraviolet photochromic anti-counterfeiting paper. |
