Document Type and Number:
Japanese Patent JP7342683
Kind Code:
B2
Abstract:
To provide an active energy ray-curable ink composition which has good adhesion to various base materials, in particular, is excellent in adhesion to base materials such as polyethylene, polypropylene and polystyrene films, and has chemical resistance of a cured coated film.SOLUTION: An active energy ray-curable ink composition contains a coloring agent, a polymerization initiator, a rosin-modified polyester compound and a (meth)acrylate compound (excluding rosin-modified polyester compound). A ratio of a structural unit derived from rosin in the rosin-modified polyester compound is 40-80 mass% based on the whole structural unit constituting the rosin-modified polyester compound.SELECTED DRAWING: None
