Abstract: The present invention relates to a multi-aziridine compound having: a) at least 2 of the following structural units (A): (A) whereby R1 is H; R2 and R4 are independently chosen from H, a linear group containing from 1 to 8 carbon atoms and optionally containing one or more heteroatoms, a branched or cyclic group containing from 3 to 8 carbon atoms and optionally containing one or more heteroatoms, phenyl, benzyl, or pyridinyl; R3 is chosen from a linear group containing from 1 to 8 carbon atoms and optionally containing one or more heteroatoms, a branched or cyclic group containing from 3 to 8 carbon atoms and optionally containing one or more heteroatoms, phenyl, benzyl, or pyridinyl; or R2 and R3 (in case R2 is different than H) may be part of the same cyclic group containing from 3 to 8 carbon atoms; R' and R'' are independently H or an aliphatic hydrocarbon group containing from 1 to 12 carbon atoms; and b) a molecular weight from 600 to 20000 Daltons, wherein the molecular weight is determined using MALDI-TOF mass spectrometry according to the description.
