<p>The invention has an object of providing paint compositions showing excellent performances in both scratch resistance and impact resistance, and processes for forming multilayer paint films using the paint composition. The invention has another object of providing paint compositions suitably used as clear paints for finish painting automobiles and the like, and highly solidifiable paint compositions. A paint composition according to the invention includes a polyisocyanate prepolymer (A) including a monomer unit of Formula (1) below and a polyol (B), and has an average functional group equivalent weight of 160 to 400 g/eq. A process for forming multilayer paint films involves the paint composition.
wherein R 1 is a hydrogen atom or a methyl group; n is an integer of 0 or 1; when n = 0, 1 = 0, p = 1 and m is an integer of 1 to 8; and when n = 1, m = 2, 1 = 2 and p is an integer of 1 to 4.</p> |
