Active energy ray-curable ink composition, inkjet recording method, and method for producing in-molded product

摘要

An active energy ray-curable ink composition includes (component A) monofunctional radically polymerizable monomers, (component B) a polyfunctional oligomer having a glass transition temperature of 20°C or lower and an acrylate value of 300 g/value or more, and (component C) a bifunctional radically polymerizable monomer having a viscosity at 25°C of 15 mPa·s or less, wherein the component A includes an N-vinyl compound and a compound represented by the following formula (I), the content of the N-vinyl compound with respect to the total amount of the ink composition is from 10 to 50% by mass, and the content of the component A with respect to the total amount of the ink composition is 70% by mass or more.
