Abstract (en)
[origin: WO9412554A1] A novel class of radiation curable oligomers having formula (I) wherein: each R is independently an organic moiety comprising at least one radiation curable moiety; each n is independently at least 1; each W is independently an organic moiety having a valence of n+1; X is oxygen or -N(R DEG )-, wherein R DEG is H, a straight-chain, branched, or cyclic alkyl group of 1 to 10 carbon atoms; or a divalent organic moiety bridging the two nitrogens of the dinucleophile; and Z is a divalent organic moiety. In another aspect, the present invention concerns a process for making the radiation curable oligomers described above. In another aspect, the present invention concerns a magnetic recording medium incorporating the radiation curable oligomers described above.
