  • Photocurable inkjet ink
    Publication number: 20080233307
    Abstract: There is a need for a photocurable inkjet ink capable of being cured with low light energy and of forming ultrafine patterns. There is also a need for the formation of films having the flexibility to be formed even on flexible boards using photocurable inkjet ink. The invention provides a photocurable inkjet ink including a photopolymerization initiator and a polymerizable monomer having a thermosetting functional group.
