Radiation-curable coating composition including oligomeric photoinitiator and/or oligomeric adhesion promoter

摘要

There is provided a radiation-curable coating composition containing oligomers that each have two end groups X¹ and X², wherein the end groups X¹ and X², which may be the same or different, are a photoinitiator group or an adhesion promoter group. The coating composition may exclude the presence of non-reactive photoinitiator groups and non-reactive adhesion promoter groups, each of which would fail to covalently bond itself to an oligomer backbone.
