Abstract
A security with a paper substrate which exhibits identifying marks in the form of color patterns. The color patterns are arranged in the substance of the paper substrate in such a manner that the normal structure of the fibres in the substance of the paper layer is not disturbed by the color patterns. In the manufacture of the security, the color pattern is sprayed on to the not yet completely finished non-woven fibre during the formation of the paper sheet, and is preferably sprayed on to a non-woven fibre which is then united to a second non-woven fibre.
