To provide a coated article having curability at normal temperature or by heating, good adhesiveness to a plastic which is a substrate and further stain resistance, adhesiveness, solvent and impact resistances and processability at the same time and further a coated article having excellent stain resistance and adhesiveness, solvent and impact resistances and processability of a topcoated acrylic silicone resin coating by use as a primer.

The curable composition for the plastic comprises 100 pts. wt. of a vinylic copolymer (A) containing a reactive silyl group-containing vinyl monomer, 0.1-80 pts. wt. of a compound (B) containing ≥2 isocyanate groups and 0.1-30 pts. wt. of an organometallic compound (C).
