ADHESIVE COMPOSITION, COPOLYEMR DISPERSION LIQUID, SET, ADHESIVE TAPE AND BONDING METHOD

WIPO Patent Application WO/2022/138131

A1

An adhesive composition which contains 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) that has a carboxy group, and a structural unit derived from a monomer (a3) that has an alkoxysilyl group; the monomer (a1) is composed of an alkyl (meth)acrylate ester that has only one ethylenically unsaturated bond and/or a hydrocarbon that has only one ethylenically unsaturated bond; the content of the structural unit derived from a monomer (a2) relative to 100 parts by mass of the structural unit derived from a monomer (a1) in the copolymer (A) is from 1.0 part by mass to 12 parts by mass; the content of the structural unit derived from a monomer (a3) relative to 100 parts by mass of the structural unit derived from a monomer (a1) in the copolymer (A) is from 0.010 part by mass to 3.5 parts by mass; the crosslinking agent (B) contains one or more compounds that are selected from the group consisting of polycarbodiimide compounds, polyepoxy compounds and polyisocyanate compounds; and the content of the crosslinking agent (B) relative to 100 parts by mass of the copolymer (A) is from 0.010 part by mass to 10 parts by mass.
