Abstract

The invention relates to a radiation curable composition comprising relative to the total weight of the composition (A) 0-29 wt % of a cationically curable component having a linking aliphatic ester group, (B) 10-85 wt % of an epoxygroup containing component other than A, (C) 1-50 wt % of an oxetanegroup containing component, (D) 1-25 wt % of a multifunctional acrylate and a radical photoinitiator and a cationic photoinitiator.
