Title:
ACTIVE ESTER COMPOUND AND CURABLE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2019/003821
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an active ester compound having a low elastic modulus under high-temperature conditions in a cured product, a curable composition containing the active ester compound, a cured product thereof, a semiconductor sealing material, and a printed wiring board. Provided are an active ester compound that is a diesterified product of a dihydroxynaphthalene compound (a1) and an aromatic monocarboxylic acid or an acid halide thereof (a2), a curable composition containing the active ester compound, a cured product thereof, a semiconductor sealing material, and a printed wiring board. The active ester compound is characterized by having a low elastic modulus under high-temperature conditions in the cured product.
