Abstract
The present invention provides energy curable compositions that are curable using UV LED radiation. The compositions comprise vinyl methyl oxazolidinone (VMOX), as well as other components generally found in energy curable inks, such as ethylenically unsaturated monomers (in addition to VMOX), acrylated oligomers, and photoinitiators. The compositions are suitable for high speed flexographic or gravure printing.
Claims20
An energy curable composition, comprising:
- (a) 1 wt % to 12 wt % vinyl methyl oxazolidinone monomer, based on the total weight of the composition;
- (b) 15 wt % to 30 wt % one or more additional monofunctional and/or multifunctional ethylenically unsaturated monomers, based on the total weight of the composition;
- wherein 0 to 10 wt % based on the total weight of the composition are monofunctional ethylenically unsaturated monomers, and 15 wt % to 30 wt % based on the total weight of the composition are multifunctional ethylenically unsaturated monomers;
- (c) 1 wt % to 30 wt % one or more acrylated oligomers, based on the total weight of the composition;
- (d) 1 wt % to 20 wt % one or more photoinitiators, based on the total weight of the composition;
- and
- wherein the energy curable composition is a finished printing ink;
- and
- wherein the energy curable composition is curable by UV LED radiation.
