Method of Improving Surface Cure in Digital Flexographic Printing Plates

摘要

A photocurable relief image printing element is described. The photocurable relief image printing element comprises (a) a support layer; (b) one or more photocurable layers disposed on the support layer, wherein the one or more photocurable layers comprise: (i) a binder; (ii) one or more monomers; (iii) a photoinitiator; and (iv) an additive selected from the group consisting of phosphites, phosphines, thioether amine compounds, and combinations of one or more of the foregoing; (c) a laser ablatable masking layer disposed on the one or more photocurable layers, the laser ablatable masking layer comprising a radiation opaque material; and (d) optionally, a removable coversheet. The photocurable relief image printing element provides improved surface cure in digital relief image printing elements.
