PROBLEM TO BE SOLVED: To provide a water dispersion type adhesive composition imparting a flat and smooth coated face on various base materials, releasing materials even in a high speed coating in which a good coated face is hard to obtain because the state of coating liquid tends to make a turbulence in a coating tank such as foaming or the like, and to provide a processed good of the same. SOLUTION: The invention relates to the adhesive composition comprising (A) a water dispersion type acrylic resin composed of (meth)acrylate as essential component and (B) a water dispersion type resin, wherein the ratio of the volumetric average particle diameter of the larger particle diameter and the smaller particle diameter in the resin (A) and the resin (B) is 0.15-0.60, and the composition manifests no lowering of torque until 8,800 rpm in measurement using Hercules high shearing viscometer and having a smooth number of revolution-torque curve in elevating and descending process of revolution and can be coated in a speed of 100-2,500 m/min and having≥60% by mass of solid resin content, and the invention relates to the pressure sensitive adhesive products composed of the adhesive composition.
