Abstract
Inkjet ink disclosed herein, usable for at least a transfer sheet suitable for an inorganic substrate, contains an inorganic solid content and a photocurable monomer component. The monomer component contains at least a monofunctional acrylate-based monomer, a monofunctional N-vinyl compound monomer, and a polyfunctional vinylether-based monomer. With respect to 100% by mass as the total weight of the monomer component, the monofunctional acrylate-based monomer is contained at a weight ratio of 40% by mass to 96% by mass, the monofunctional N-vinyl compound monomer is contained at a weight ratio of 2% by mass to 20% by mass, and the polyfunctional vinylether-based monomer is contained at a weight ratio of 2% by mass to 40% by mass.
