It is an object of the present invention to provide a water-based one-pack-type coating composition which can form a coating film having a satisfactory feel of achieving a soft feel and coating film performance simultaneously and further maintains common performance of paint such as excellent design (a matt appearance, etc.), an adhesion property, coating film strength, abrasion resistance, water resistance, oil and grease-contamination resistance. A water-based one-pack-type coating composition of the present invention comprises: an ionomer resin emulsion (A), a polyolefin resin emulsion (B), resin particles (C), and a urethane dispersion (D), wherein a solid content mass ratio (mass ratio as converted into a solid content) of (C)/{(A)+(B)+(D)} is 40/100 to 100/100, a solid content mass ratio of (A)/(B) is 1/3 to 3/1, and a solid content mass ratio of {(A)+(B)}/(D) is 40/60 to 70/30.

Water-based one-pack-type coating composition and coated article

The present invention provides a coating composition for automotive upholstery, with which a 1-coat finish of not yet surface-treated (pretreated) plastic materials such as polyolefin materials can be performed, and which is aqueous, and excellent also in chemical resistance. The aqueous coating composition for automotive upholstery comprises a resin emulsion as an essential component, wherein the resin emulsion includes poly(olefin chloride) resin emulsion A and pure acrylic resin emulsion B in a weight ratio (A/B) of 25/75&tilde;30/70 in terms of solid content, wherein poly(olefin chloride) resin emulsion A is an emulsion of a poly(olefin chloride) resin having a chlorine content of 22&tilde;25 wt % in terms of solid content and a weight-average molecular weight of 60,000&tilde;80,000, and wherein pure acrylic resin emulsion B is an emulsion of a pure acrylic resin having a glass transition temperature of not lower than 40&deg; C.
