PROBLEM TO BE SOLVED: To provide a solvent type printing ink composition for extrusion lamination which has high adhesiveness to a plastic film and is excellent in lamination suitability even in extrusion lamination processing.SOLUTION: A solvent type printing ink composition for extrusion lamination contains a pigment, a binder resin, a chelate crosslinking agent, and an organic solvent. The chelate crosslinking agent comprises a reactant of tetraisopropoxy titanium and 2-ethylhexanoic acid, and/or a zirconium propionate, and contained at 0.1-5 wt% in the solvent type printing ink composition for extrusion lamination. The binder resin comprises a polyurethane resin and a cellulose derivative, and contains them so that a content ratio of the polyurethane resin to the cellulose derivative is in a range of from 100:0 to 50:50 (by weight). The organic solvent does not contain aromatic hydrocarbon-based organic solvent. |
