Abstract: An object of the present invention is to provide an aqueous dispersion composition containing polyester resin having high storage stability, film-forming properties, tackiness, adhesiveness, and water resistance. An aqueous dispersion composition containing polyester resin, comprises, a polyester resin (A), a coalescing aid (B), and an aqueous medium (C), wherein the coalescing aid (B) has a Hansen solubility parameter with a dispersion term (δd) of 15.4 MPa0.5 or more and less than 18.0 MPa0.5, a polarization term (δp) of 4.1 MPa0.5 or more and less than 9.1 MPa0.5, and a hydrogen bond term (δh) of 7.0 MPa0.5 or more and less than 12.3 MPa0.5.
