Radiation-curable oligomers and magnetic recording media prepared therefrom (RADIATI0N CURABLE OLIGOMERS AND MAGNETIC RECORRING MEDIA PREPARED THEREFORM)

摘要

present invention relates to novel radiation curable oligomers of general formula (I).;Wherein each R is an organic moiety each containing at least one radiation curable moiety; Each n is 1 or more; Each W is each n + 1 valent organic moiety; X is oxygen or-N (R⁰)-, and R⁰H, C_One-C₁₀Branched or cyclic alkyl group, or a divalent organic moiety connecting two nitrogens of a dinucleophile; Z is a divalent organic moiety.;As a second aspect of present invention, present invention relates to a method for producing above-mentioned radiation-curable oligomer. As a third aspect of present invention, present invention relates to a magnetic recording medium comprising above radiation-curable oligomer.
