<p>PROBLEM TO BE SOLVED: To provide an acrylic resin composition for a coating material that has excellent in characteristics balance among adhesion, water resistance, and oil and fat resistance when applied to an automobile component using a thermoplastic resin being inferior in adhesion as a material.SOLUTION: The acrylic resin composition comprises a polymer (A), a polymer (B) and a graft polymer(C). The constitutional unit of the polymer (A) is a monomer component (a) including a benzyl methacrylate and a (meth)acrylic acid ester other than the benzyl methacrylate; the constitutional unit of the polymer (B) is a monomer component (b) including a (meth)acrylic acid ester other than the benzyl methacrylate; and the constitutional unit of the graft polymer (C) is composed of the monomer component (a) as a stem part and the monomer component (b) as a branch part. The acrylic resin composition has a glass transition point temperature of 75-100°C and a weight average molecular weight of 50,000-150,000.</p> |
