Disclosed is an acrylic sol for a sound insulating underbody coating. It includes acrylic polymer fine particles, a plasticizer, a filler, a plasticizer, a blocking type urethane resin, a curing agent and a foaming agent. Since it includes the acrylic polymer particles as a major constituent unit, it does not generate a hydrogen chloride gas and dioxins when it is burned. Moreover, since the paint film resulting from the acrylic sol has a net-shaped structure by the cross-linkage reactions of the urethane resin, and since the bulkiness of the paint film is increased by the foaming agent, it has a good cold resistance and adhesion property toward automotive steel plates, and effects a superb chipping resistance and sound insulating performance.
