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.

摘要:
A process for making dendritic hydrocarbon polymers by reacting an amount of one or more telechelic hydrocarbon polymers with an amount of one or more multifunctional coupling agents under conditions sufficient to produce the dendritic hydrocarbon polymer. The telechelic hydrocarbon polymer is made by ring opening metathesis polymerization (ROMP) in the presence of bi-functional alkene chain terminating agents (CTAs). The dendritic hydrocarbon polymer can be hydrogenated to produce a substantially saturated dendritic hydrocarbon polymer. The dendritic polyethylenes (dPE) can be used as processability additives to provide extensional hardening in low concentrations in various conventional polyethylenes (PEs) such as HDPE, LLDPE and mLLDPE.
