PROBLEM TO BE SOLVED: To provide an acrylic resin composition for coating excellent in weather resistance and a plastic molded article using it. SOLUTION: The acrylic resin composition for coating comprises an acrylic copolymer comprising (A) 1-60 mol% of an acrylate repeating unit having a methyl group ((A-1) unit), >35 mol% and ≤85 mol% of an acrylate repeating unit having a cycloalkyl group ((A-2) unit), 0.1-15 mol% of an acrylate repeating unit having a UV light absorbing group ((A-3) unit), and 1-15 mol% of an acrylate having at least one substituent selected from the group consisting of a hydroxy group, an alkoxysilyl group, a glycidyloxy group and an isocyanate group ((A-4) unit), in which the total of (A-1)-(A-4) units is at least 70 mol% based on the total repeating units of the acrylic copolymer of 100 mol%.
