Beschreibung
Zusammenfassung:	The invention is in the field of papermaking. It provides methods for improving the compressive strength of paper and board by improving the moisture resistance of paper and board. The invention also provides paper and board with an improved compressive strength as well as a composition for improving the compressive strength of paper and board. More in particular, the invention relates to a process for the manufacture of paper wherein the process comprises a wet phase and a dry phase, wherein an enzymatically oxidized lignin is added in the wet phase.
