Document Type and Number:
WIPO Patent Application WO/2022/138132
Kind Code:
A1
Abstract:
This adhesive composition comprises a copolymer (A), a crosslinking agent (B), and an aqueous medium, wherein: the copolymer (A) has a structural unit derived from a monomer (a1), a structural unit derived from a monomer (a2) having a carboxy group, and a structural unit derived from a monomer (a3) having an epoxy group; the monomer (a1) is composed of one or both of alkyl (meth)acrylate having only one ethylenically unsaturated bond and hydrocarbon having only one ethylenically unsaturated bond; the content of the structural unit derived from the monomer (a2) with respect to 100 parts by mass of the structural unit derived from the monomer (a1) in the copolymer (A) is 1.0-12 parts by mass; the content of the structural unit derived from the monomer (a3) with respect to 100 parts by mass of the structural unit derived from the monomer (a1) in the copolymer (A) is 0.10-10 parts by mass; the crosslinking agent (B) contains at least one selected from the group consisting of a polycarbodiimide compound, a polyepoxy compound, and a polyisocyanate compound; and the content of the crosslinking agent (B) with respect to 100 parts by mass of the copolymer (A) is 0.010-10 parts by mass.
