An adhesive composition is provided. The adhesive composition comprises the following components: (a) a polyacid polymer aqueous dispersion, wherein the polyacid polymer contains 50%～100%by weight of one or more ethylenically unsaturated mono-or dicarboxylic acid/anhydrides; (b) a hydroxyl group-containing acrylic copolymer emulsion, wherein the hydroxyl group-containing acrylic copolymer is obtained from polymerizing a monomer mixture which contains 0.1-10%hydroxyl group-containing monomer, 0.1%to 20%weight unsaturated carboxylic acid and 30%-90% acrylic monomer, wherein the solid weight ratio of the above components (a) and (b) is 0.1: 100 to 10: 100, based on the solids of the components (a) and (b). |
