PROBLEM TO BE SOLVED: To obtain the subject composition comprising an acrylic copolymer having a glass transition point in a specified range and an adhesivity-imparting resin having a softening point in a specified range in specific amounts, respectively, having the average particle diameters of the components in specific ranges, respectively, and excellent in curved surface adhesivity, etc. SOLUTION: This acrylic aqueous pressure-sensitive composition is produced by dispersing (A) 70-98wt.% of an acrylic copolymer having a glass transition point of <=-40 deg.C and (B) 2-30wt.% of an adhesivity-imparting resin having a softening point of 70-180 deg.C and a weight-average mol.wt. of <=5000 on the basis of 100wt.% of the total amount of the components A and B in an aqueous medium. The average particle diameter of the dispersed particles of the component A is >0.3μm, and the average particle diameter of the dispersed particles of the component B is <=0.3μm. The component B is preferably a terpene-phenol resin, a rosin resin or a petroleum hydrocarbon resin.
