| 摘要 |
An improved photopolymerizable resin composition for use in making flexographic printing plates, wherein the resin composition comprises a base polymer, a reactive crosslinking agent, a photoinitiator, and a nanoparticle-sized filler. Printing plates produced using the improved compositions of the invention have increased toughness, less tack, reduced cold flow, and higher hardness as compared to prior art compositions that do not contain nanoparticle fillers.
