| 摘要 |
The invention relates to a security paper with at least two types of mottled fibres, which differ in terms of their luminescent characteristics and form a code. In each case one type of mottled fibres is present in a defined subarea of the security paper, and the code is represented by the defined geometric arrangement of the subareas on the security paper and/or by the presence or absence of mottled fibres of a specific type.
