Document Type and Number:
WIPO Patent Application WO/2022/114097
Kind Code:
A1
Abstract:
In order to obtain an adhesive composition having exceptional adhesive properties and moist heat resistance as well as low permittivity and a low dielectric loss tangent, provided is an adhesive composition containing an acrylic resin (A) and a hydrophilicity-imparting agent (B), wherein: the acrylic resin (A) is a copolymer of a copolymer component (a) that contains a methacrylic acid alkyl ester monomer (a1) having a C10-36 alkyl chain, and a polar-group-containing ethylenic unsaturated monomer (a2); the polar-group-containing ethylenic unsaturated monomer (a2) content is less than 3 wt% relative to the copolymer component (a); and the hydrophilicity-imparting agent (B) is a compound (B1) that has a –(CnH2nO)m- (where n is 2-6, and m is 2-25) structure and that contains at least one ethylenic unsaturated group.
