A hydroxyl group-containing resin (A) having a hydroxyl value of 80 to 200 mg KOH / g and a weight average molecular weight of 2500 to 40000, a polyisocyanate compound (B), and a diol having 2 to 10 carbon atoms as a carbonylating agent A coating composition containing a polycarbonate diol compound (C) having a number average molecular weight of 400 to 2500 having a viscosity at 50 ° C. of 10,000 mPa · s or less obtained by reaction. A cured coating film excellent in any of scratch resistance, acid resistance, stain resistance and finish can be formed. |
