Abstract

This invention provides an inkjet ink or ink assembly that can be used to form a hardened film by light irradiation and heating, and which is not prone to peeling at the lamination interface. The invention relates to a curable composition comprising a compound having a (meth)acrylic group and a compound having an epoxy group. The aforementioned curable composition is contained within the hardened film and exists as a dispersed elastomer. The aforementioned curable composition can be a single-component inkjet ink or a multi-component inkjet ink assembly.
