The polycarbonate-modified acrylic resin has high adhesion to a plastic substrate and is capable of forming a coating film having excellent abrasion resistance, chemical resistance, feel, and appearance. Therefore, the polycarbonate-modified acrylic resin can be suitably used for a coating.

Abstract: A resin composition is proved which is obtained by a polymerization reaction of a vinyl monomer mixture in the presence of an acid modified polyolefin resin, the vinyl monomer mixture containing as an essential component, a phosphorus atom-containing vinyl monomer and at least one type of vinyl monomer selected from the group consisting of ethyl acrylate, n-butyl acrylate, and 2-ethylhexyl acrylate and having a glass transition temperature of ?5° C. to 45° C. which is calculated by FOX's equation. In the resin composition described above, the mass ratio of the vinyl monomer mixture to the acid modified polyolefin resin is in a range of 99/1 to 60/40. Since capable of forming a coating film which has a high adhesion to a plastic and a top coating film and an excellent water resistance, this resin composition can be preferably used for a primer coating material.
