Clear coating composition and method for producing coated article

A method for producing a coated article, comprising:

• applying a base coating composition onto an article to be coated to form an uncured base coating film;
• applying a clear coating composition to the uncured base coating film to form an uncured clear coating film;
• and
• simultaneously curing the uncured base coating film and the uncured clear coating film,
• wherein the clear coating composition includes:
• a hydroxy group-containing acrylic resin (A);
• a polyisocyanate compound (B);
• and
• an organic solvent (C),
• wherein the hydroxy group-containing acrylic resin (A) includes a primary hydroxy group-containing acrylic resin (A1) and a secondary hydroxy group-containing acrylic resin (A2),
• the primary hydroxy group-containing acrylic resin (A1) does not contain a secondary hydroxy group,
• the primary hydroxy group-containing acrylic resin (A1) has an acid value of 0 mg KOH/g or more and 40 mg KOH/g or less,
• the primary hydroxy group-containing acrylic resin (A1) has a weight average molecular weight (Mw) of 6,000 or less,
• the secondary hydroxy group-containing acrylic resin (A2) has a weight average molecular weight (Mw) of 6,000 or more,
• the organic solvent (C) includes a ketone compound having 7 or 8 carbon atoms (C1), and
• the clear coating composition has a solid concentration at a time of application of 55% by mass or more.
