Claims14
Paper (1), in particular a purely fiber-based paper, the surface of which comprises a coating (3) on one or both sides characterized in that a water-soluble primer layer (4) is applied to the coating.
Finishing method (7) for a paper (1), in particular purely fiber-based paper, comprising the following process steps, namely:
- provision of a base paper (7) comprising a coating (3) on one or both sides, and
- application of a water-soluble primer layer (4) to the coating (3).
Use of a water-soluble primer layer on a coating (3) of a paper (1), in particular a purely fiber-based paper, on the one hand to provide a water-based separability of the fiber material of the paper (1) from the primer layer (4) and on the other hand to at least reduce the tendency of the coating to break when the paper (1) is used folded.
