| abstract |
A radiation curable composition including na) at least one monomer comprising at least one vinyl ether group and at least one (meth)acrylate group; and nb) at least one diffusion hindered photoinitiator selected from the group consisting of a polymeric photoinitiator, a multifunctional photoinitiator and a polymerizable photoinitiator ncharacterized in that the diffusion hindered photoinitiator comprises at least one structural moiety according to Formula (I):n nwherein: nR1 and R2 are independently selected from the group consisting of a hydrogen, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkynyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted alkaryl group, a substituted or unsubstituted aryl or heteroaryl group, a halogen, an ether, a thioether, an aldehyde, a ketone, an ester, an amide, an amine and a nitro group; nR1 and R2 may represent the necessary atoms to form a five to eight membered ring; and nthe dotted line represents the covalent bond of the structural moiety according to Formula (I) to the diffusion hindered photoinitiator. n n n An inkjet printing method using the radiation curable composition is also disclosed. |
