Abstract: This invention pertains to security paper and methods of making such security paper. The invention comprises a light-colored base paper having a non-protection area of a first thickness, and a protection area of a second thickness on at least one major surface of the base paper wherein the first thickness is greater than the second thickness. The base paper comprises colorant whereby the protection area exhibits a translucence when viewed using transmitted light, and exhibits the colorant as a darker color indication, relative to the non-protection area, when viewed using reflected light. Transmission of light through a combination of paper fibers and the colorant of the invention, both being disposed at the protection area, is discernibly different from transmission of light through the non-protection areas of the base paper, when viewed with a human eye.

Abstract translation: 本发明涉及安全性文件及其制作方法。 本发明包括具有第一厚度的非保护区域的浅色原纸和在原纸的至少一个主表面上的第二厚度的保护区域，其中第一厚度大于第二厚度。 原纸包括着色剂，由此当使用透射光观察时，保护区域表现出半透明度，并且当使用反射光观察时，相对于非保护区域，着色剂显示为较暗的颜色指示。 当通过人眼观察时，通过纸纤维和本发明的着色剂组合的光的两个被布置在保护区域的透射可以不同于通过原纸的非保护区域的光的透射。
