Claim Text:
1. A method for producing a security element with negative writing for a security paper or an object of value such as a value document, comprising the steps: a) producing a first security-element partial element by b) producing a second security-element partial element by c) assembling the first and the second security-element partial elements to a composite such that the resist layer and the second functional layer face each other, and bonding the first and the second security-element partial elements, and d) detaching the second carrier substrate from the bonded composite, whereby the second functional layer adheres to the resist areas so as to form second functional areas, while the remaining areas of the second functional layer are detached together with the second carrier substrate, thereby forming in the second functional layer second gaps which, together with the gaps in the resist layer and the first gaps in the first functional layer, form the negative writing.
