| description | Provided is a coating material composition that enables an efficient repair operation of a coating film after coating, a (meth)acrylic copolymer that is suitable for obtaining the coating material composition, and a coated article and a method for forming a multilayer coating film using the coating material composition. The (meth)acrylic copolymer includes: a constituent unit derived from a macromonomer (a); and a constituent unit derived from a vinyl monomer (b), a hydroxyl value of the (meth)acrylic copolymer is equal to or greater than 120 mgKOH/g and equal to or less than 260 mgKOH/g, and the content of a constituent unit that has a primary hydroxyl group of the (meth)acrylic copolymer is equal to or less than 30 parts by mass with respect to 100 parts by mass of the constituent unit derived from the macromonomer (a) and the constituent unit derived from the vinyl monomer (b). |
