<p>The present invention is a printed matter which comprises a colorant, multiple resins and an additive and is formed on a polyolefin resin substrate, wherein at least one type of the resins is a chlorine-based resin and concentration of the chlorine-based resin in the printed matter is higher in the vicinity of a printing substrate interface which is the interface between the substrate and the printed matter than in the vicinity of an air interface which is the interface between the air and the printed matter. Additionally, the present invention is an ink for an ink jet printer comprising a colorant, a resin and a solvent, wherein a chlorine-based resin is used as the resin, and the solvent is composed of a main solvent and a subordinate solvent, the steam pressure of the main solvent at 20°C being 9.0 kPa or more and the steam pressure of the subordinate solvent at 20°C being 0.6-2.0 kPa. Thus, improvement in adhesion between the printed matter and the polyolefin resin substrate and load reduction for the device can both be achieved.</p> |
