Document Type and Number:
WIPO Patent Application WO/2019/172109
Kind Code:
A1
Abstract:
Provided is an adhesive composition that is characterized by containing a modified polypropylene-based resin (A), an epoxy resin (B) and an unmodified polypropylene-based resin (C), with the modified polypropylene-based resin (A) being a resin obtained by graft modifying an unmodified polypropylene-based resin (D) with a modifying agent that contains an α,β-unsaturated carboxylic acid or a derivative thereof, the content of the modified polypropylene-based resin (A) being 10 mass% or more in terms of solid content, and the content of the unmodified polypropylene-based resin (C) being 1-90 mass% in terms of solid content. The adhesive composition exhibits good adhesion to a copper foil or a base material film comprising a polyimide resin or the like, and exhibits improved dielectric properties.
