Abstract
There is provided a coating composition with excellent storage stability, and with excellent mar resistance for obtained coating films. The coating composition comprises a hydroxyl group-containing resin (A), a curing agent (B) and a dispersion of acrylic resin-coated silica particles (C), the dispersion of acrylic resin-coated silica particles (C) being an acrylic resin-coated silica particle dispersion obtained by reacting silica particles with a polymerizable unsaturated group (c1) and a polymerizable unsaturated monomer (c2) in a mass ratio of (c1):(c2)=20:80 to 90:10, the polymerizable unsaturated monomer (c2) including a specific polymerizable unsaturated monomer (c2-1) as at least a portion of its components, and the molecular weight of the resin covering the silica particles being 400 to 6000.
