    Abstract: The present invention provides a polyolefin-based composite resin spherical particle that gives a coating film having a matte appearance, a soft feeling, and excellent scratch resistance by being used for a coating material. The present invention also provides a coating composition containing the polyolefin-based composite resin spherical particle and a coating resin, and a coated article obtained by applying the coating composition to a substrate.The invention relates to a polyolefin-based composite resin spherical particle, which is a spherical particle obtained by mixing 100 parts by mass of a polyolefin-based resin, 40 to 1,500 parts by mass of water, and 3 to 30 parts by mass of an ethylene oxide/propylene oxide copolymer having a weight average molecular weight of 4,000 to 30,000 to prepare a mixture, emulsifying the mixture at a temperature of the highest melting point of the polyolefin-based resin or higher, and cooling the mixture from a temperature at least 25° C. higher than the highest crystallization temperature of the polyolefin-based resin to a temperature at least 25° C. lower than the lowest crystallization temperature of the polyolefin-based resin at a cooling speed of 0.2° C./min or more, wherein the polyolefin-based resin is a composite resin containing 5 to 70% by mass of a partially saponified ethylene/vinyl acetate copolymer.
