Active energy ray-curable ink for lithographic offset printing, its manufacturing method, manufacturing method of ink cured product and printed matter

摘要

PROBLEM TO BE SOLVED: To provide an active energy ray-curable ink for lithographic offset printing, which is suitable for lithographic offset printing and has further excellent fluidity and stability. SOLUTION: The active energy ray-curable ink for flat plate offset printing containing a monomer having an ethylenically unsaturated double bond, a metal complex, a compound having a polar group, a pigment, and a pigment dispersant containing a polar group, the ink. A manufacturing method for flat plate offset printing in which a metal complex and a compound having a polar group are mixed and dispersed in advance, and then a monomer having an ethylenically unsaturated double bond, a pigment, and a polar group-containing pigment dispersant are mixed and dispersed. A method for manufacturing an active energy ray-curable ink. [Selection diagram] None
