Document Type and Number:
WIPO Patent Application WO/2023/188507
Kind Code:
A1
Abstract:
The present invention provides: a resin composition for forming a low-dielectric adhesive layer that has excellent 5G-compatible electrical properties (low-dielectric properties), ensures high adhesiveness, suppresses the occurrence of air bubbles, and exhibits a small linear coefficient of thermal expansion (CTE); and an adhesive composition containing said resin composition. This adhesive composition contains a resin composition containing: a maleimide resin having a molecular weight of 1,000 or more; and a benzoxazine resin. The benzoxazine resin has a site represented by formula (1). (In formula (1), R represents a hydrocarbon group having 4 or more carbon atoms. The hydrocarbon group may have an unsaturated bond site.)
