To provide a clear coat covering composition for a clear coat layer in a two layer (base coat/clear coat)-covered product.
The clear coat covering composition includes a resin solid matter comprising 60-70 mass% of a binder solid matter and 30-40 mass% of a trimer of a 1,6-hexane diisocyanate cross-linking agent. The binder solid matter includes 60-100 mass% of a (meth)acrylic copolymer resin A. The monomer composition of the resin A includes (a) a (meth)acrylic acid corresponding to the ratio of an acid value of 5-10 mg-KOH/g, (b) a (meth)acrylic monomer having a primary OH group corresponding to the ratio of an OH value of 120-150 mg-KOH/g, and with respect to the amount of (meth)acrylic monomer having a primary OH group, 50-100 mol% of a 1,4-butane diol monoacrylate, (c) 15-25 mass% of a styrene, and (d) 15-50 mass% of one or more of 4 to 12C alkyl (meth)acrylate.
