The present invention provides an in jet recording medium which is capable of uniform coating with an ink-receiving agent without a surface treatment step for a usual plastic film used as a base material, and which, due to excellent adhesion between a plastic film and a receiving agent, does not cause the problem of peeling or the like after ink jet printing, and further does not cause the problem of ink blurring, fading, dropout, or peeling or peeling of an ink-receiving layer and an over-coating layer, or the like during an over-coating treatment, and also provides a printed material formed by ink jet printing on the ink jet recording medium, a method for producing the same, and a packaging material composed of the printed material. Specifically, an ink jet recording medium including a layer (A1) containing a polyolefin resin as a main component, a layer (A2) containing an acid-modified olefin resin, and an ink-receiving layer (B) is used, the ink-receiving layer (B) being formed by applying an ink-receiving agent on the layer (A2) after the layers (A1) and (A2) are laminated by a coextrusion laminating method.
