ABSTRACT:
Disclosed is a two-part adhesive comprising: (A) an aqueous emulsion liquid having a polymer component and an emulsifier component, in which at least one of the polymer component and the emulsifier component contains an anion radical; and (B) a solution having an amino-radical-containing acrylic copolymer. The amount of the polymer component in the aqueous emulsion liquid is within a range of from about 20% to about 80% by weight. When the aqueous emulsion liquid (A) contacts the solution (B) on an adherend surface, they form sticky gel adhesive.
