Abstract (en)
[origin: WO2019086080A1] The invention relates to a method for producing a security feature on a security paper, in which method a security paper (1) is generated by means of a paper production process and thereby a colour security feature (6) is designed on the security paper (1), wherein, in order to design the colour security feature (6), a colouring agent is applied during the paper production process at least locally to an intermediary product (5) of the security paper by means of a colour application method, said intermediary product being not yet dried or not yet completely dried, and the intermediary product (5) is subsequently dried or further dried. The invention also relates to the use of a produced security paper having the security feature in order to produce a security document.
