Estimating the term…
The present invention provides a recording medium for an ink jet ink, which is capable of printing directly with an ink jet ink without a surface treatment step necessary for use of an ordinal plastic film as a substrate and which causes no problem of peeling or the like after printing, and also provides a printed material produced by ink jet printing on the recording medium and a production method therefor. Specifically, printing is performed with various ink jet inks on a layer (A) of a single-layer or multi-layer film (I) used as a recording medium, the layer (A) containing a cyclic polyolefin resin or an acid-modified polyolefin resin.
A method for producing an ink jet printed material comprising ink jet printing on a surface of a layer (A) of a single-layer or multi-layer film (I) including the layer (A), the layer (A) containing a cyclic polyolefin resin (a1) and/or an acid-modified polyolefin resin (a2).
A recording medium for an ink jet ink comprising a laminate of a layer (A) containing a cyclic polyolefin resin (a1) and/or an acid-modified polyolefin resin (a2) and a layer (B) containing a polyolefin resin (b), wherein a thickness ratio of the layer (B) to a total thickness of the layer (A) and the layer (B) is 5 to 85%, and a surface of the layer (A) has 40 dyne/cm or more.
