<p>PROBLEM TO BE SOLVED: To provide an ultraviolet ray-curable screen ink composition which have all of dryability and smoothness of screen-printed coating as well as inkjet print quality, by adding a small amount of photopolymerization initiator without using an especially reactive polyfunctional monomer.SOLUTION: The present invention is completed by finding that prior addition of water to an ultraviolet ray-curable composition exhibits a remarkable effect to solve the problem. That is, the ultraviolet ray-curable screen ink composition comprises a water-soluble monomer, a water-soluble polymer, a filler, a photopolymerization initiator, and water.</p> |
