(57) [Summary] [Purpose] To develop an adhesive with excellent initial adhesiveness, adhesive strength and water resistance. [Structure] (A) Methacrylic acid ester-based monomer (methyl methacrylate, etc.) unit, acrylic acid ester-based monomer (n-butyl acrylate, etc.) unit, styrene-based monomer (styrene, etc.) unit, diene-based monomer At least one hydrophobic unsaturated monomer unit such as a monomer (such as butadiene) unit and a halogenated unsaturated monomer (such as vinyl chloride) unit and a primary hydroxyl group-containing ethylenically unsaturated monomer (2 -Hydroxyethyl acrylate, etc.), an aqueous emulsion containing a dispersoid composed of a copolymer composed of units and a dispersant composed of a polyvinyl alcohol-based polymer having a mercapto group at a terminal, and a composition composed of (B) a polyvalent isocyanate compound, And an adhesive comprising the composition, and a wood product obtained by adhering with the adhesive. |
