SOLUBLE IMIDE-SKELETON RESIN, SOLUBLE IMIDE-SKELETON RESIN SOLUTION COMPOSITION, CURABLE RESIN COMPOSITION, AND CURED PRODUCT THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an imide-skeleton resin which has a low linear expansion coefficient that is about the same as that of a polyimide resin, is excellent in moldability like an epoxy resin, and is useful for a resin composition for an electric laminate.

SOLUTION: The imide-skeleton resin is a reaction product of an imide-skeleton-including bisphenol and epichlorohydrin or a product prepared by converting a terminal epoxy group of the reaction product to a terminal hydroxyl group. The imide-skeleton resin includes an imide-skeleton-including linkage represented by general formula (4-1), as a bisphenol residue, in a quantity of at least 5 mol% of the components.
