PURPOSE: An aqueous acrylic emulsion-type pressure-sensitive adhesive, and a manufacturing method thereof are provided to secure the adhesion force of an oily adhesive level, and the storage stability. CONSTITUTION: An aqueous acrylic emulsion-type pressure-sensitive adhesive contains an acrylic emulsion produced by polymerizing emulsion liquid with 100 parts of monomer mixture by weight, and 5~30 parts of tackifier by weight. The monomer mixture contains the following: 60~90wt% of alkyl acrylate, alkyl methacrylate, or their mixture; 5~30wt% of aryl ester, vinyl ester, unsaturated acetate, or their mixture; 0.5~5wt% of unsaturated carboxylic acid, a hydroxyl group-containing unsaturated monomer, or their mixture; 0.1~3wt% of epoxy group-containing unsaturated monomer; and 0.1~3wt% of cross-linking agent. |
