<p>Provided is a clear coating composition capable of forming a cured film (for example, coating film) that exhibits excellent mar resistance (abraded mar resistance), design characteristic, acid resistance (sulfuric acid resistance), and yellowing resistance, simultaneously. A curable resin composition comprising a hydroxyl group-containing acrylic resin and a polyisocyanate compound as a curing agent, wherein the composition is a clear coating composition containing as the hydroxyl group-containing acrylic resin a polycarbonate diol-grafted acrylic resin produced via polymerization of a polycarbonate diol-modified monomer obtained by reaction of a hydroxyalkyl group-containing ethylenically unsaturated monomer, a diisocyanate compound having two isocyanate groups differing from each other in reactivity with hydroxyalkyl, such as isophorone diisocyanate, and a polycarbonate diol.</p> |
