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.

Claim (Index 1):
A coating composition comprising (A) a hydroxyl group-containing resin, (B) a curing agent and (C) a dispersion of acrylic resin-coated silica particles, wherein the dispersion of acrylic resin-coated silica particles (C) is an acrylic resin-coated silica particle dispersion that is the reaction product of 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) includes, as at least a portion of its components, a polymerizable unsaturated monomer (c2-1) represented by the following formula (I): (wherein R 1  represents a hydrogen atom or a methyl group, Z represents a structure including the following formula (II), and X represents a hydrogen atom or a (meth)acryloyl, alkyl, hydroxyl, amino, (alicyclic) epoxy, carboxyl, mercapto, vinyl, isocyanate or aryl group). (wherein m represents a number of 5.5 to 160, R 2  represent phenyl groups or alkyl groups of 1 to 6 carbon atoms, which may be the same or different, and R 3  represents an alkylene group of 1 to 6 carbon atoms), and the molecular weight of the resin covering the silica particles is 400 to 6000.
