<p> The present invention provides an ink composition, the cured product of which has rubber-like stretch and elasticity. According to the present invention, there is provided an ink composition containing: a photocuring type reactive compound having a monofunctional monomer and a polyfunctional monomer; and a photopolymerization initiator, the molar fractions of the monofunctional monomer and the polyfunctional monomer, expressed as the ratio of monofunctional monomer/polyfunctional monomer, being equal to 92/8-99.9/0.1. The monofunctional monomer and/or the polyfunctional monomer has hydroxyl groups or amino groups, the molar fraction of the aforementioned moiety structures being 5-30% of the entire amount of the monofunctional monomer and the polyfunctional monomer.</p> |
