Beschreibung
Zusammenfassung:	The present invention relates to an inkjet composition having 1.0 - 4.5 mol/kg acryloyl groups comprising:i) photo polymerization reactive compound (M) containing exactly one acryloyl group,ii) photo polymerization reactive compound (N) containing at least two acryloyl groups,iii) radical photoinitiator (R),iv) epoxy compound (D) containing at least two epoxy groups andv) epoxy curing catalyst (C), wherein(M) is different from (D) and (N) is different from (D),25 - 50 mol % of the contained acryloyl groups are provided by the reactive compound (N) and the molar ratio of contained acryloyl groups to contained epoxy groups of compound (D) is 0.3 to 1.5.
