EPOXY RESIN COMPOSITION, RESIN SHEET, CURED ARTICLE, AND PHENOXY RESIN

摘要

An epoxy resin composition comprises: (i) an epoxy resin; (ii) a curing agent; and (iii) a non-crystalline phenoxy resin which is represented by general formula (1) [wherein X represents a biphenylene skeleton represented by formula (2) (wherein R1 to R8 independently represent a hydrogen atom or a linear or branched alkyl group having 1 to 4 carbon atoms) or a naphthalene skeleton represented by formula (3); Y represents a biphenylene skeleton represented by formula (2); Z represents a hydrogen atom or a glycidyl group; and n represents the number of repeating units] and has a weight average molecular weight falling within the range from 10,000 to 200,000. The component (i) contains a crystalline epoxy resin having a mesogenic group in an amount falling within the range from 5 to 100 wt% relative to the total amount of the component (i).
