Title:
ACTIVE ESTER COMPOUND
Document Type and Number:
WIPO Patent Application WO/2018/207532
Kind Code:
A1
Abstract:
Provided are: an active ester compound that exhibits excellent dielectric characteristics and copper foil adhesiveness in a cured product; a curable composition comprising the same and a cured product thereof; and a semiconductor sealing material, a printed circuit board, and a build-up film which comprise the curable composition. More specifically, provided are: an active ester compound comprising, in a molecular structure, a fluorinated hydrocarbon structural site (F) and a plurality of aromatic ester structural sites (E), and at a molecular terminal, an aryloxycarbonyl structure (P) or an arylcarbonyloxy structure (A); a curable composition comprising the same and a cured product thereof; and a semiconductor sealing material, a printed circuit board, and a build-up film which comprise the curable composition.
