The present invention relates to a lignin-based binder, a lignin-based two-component (2K) adhesive and the use thereof, in particular for bonding wood chips and wood fibers for the production of chipboard, OSB, MDF-HDF boards , Plywood and plywood materials. For this purpose, the binder contains a) a first monomer of the general structure Y- (C) -X and / or its cyclic condensation product with a total content of 15 to 40 wt .-%, wherein X and Y independently of one another a carboxyl group (COOR) or amino group (-NHR), C is an optionally substituted (CHR) n group or C5-10 alicyclic cycle, n is an integer between 1 and 10, R is hydrogen (H) or a C1-6 alkyl group, b) Alkali lignin having a molecular weight of 2000 to 4000 g / mol with a total content in the range of 40 to 85 wt .-%, wherein the lignin is monomolecularly present in the monomer.
