US 11,898,044 B2 · Ink composition

Abstract

An active energy ray curable ink composition capable of improving curability while maintaining excellent metal-tone glossiness and a printed matter having high design properties and excellent metal-tone glossiness. The ink composition is discharged using an inkjet method, and contains a polymerization initiator, a polymerizable compound, and a brilliant pigment. The polymerization initiator contains an acylphosphine oxide-based polymerization initiator, aminoacetophenone-based polymerization initiator, and thioxanthone-based polymerization initiator. The printed matter includes a brilliant layer containing the brilliant pigment.
