<P>PROBLEM TO BE SOLVED: To provide an ink that has viscosity suitable for being used as an inkjet ink and shows excellent curing performance. <P>SOLUTION: The energy-curable inkjet ink comprises an epoxide monomer, a cationic photoinitiator other than a sulphonium initiator, and γ-butyrolactone and an optional oxetane monomer that exhibits a satisfactory level of cure and has a sufficiently low viscosity to be employed in inkjet printing. The weight ratio of epoxide monomer to γ-butyrolactone is within the range of from 15:1 to 2.5:1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
