Abstract

A coating composition having (A) an alcohol dispersion which includes silica having the hydrophobic surface and dispersed in an alcohol dispersion medium, the content of silica in a solid substance being 80% by weight or more; (B) a solution including a silicone oligomer which is obtained by a reaction of an alkoxysilane with water and has an average structural unit represented by R.sup.1.sub.n SiO.sub.x/2 (OH).sub.y (OR.sup.2).sub.z (R.sup.1 representing an alkyl group, phenyl group or vinyl group, R.sup.2 representing an alkyl group and n, x, y and z representing numbers satisfying relations: 0.8.ltoreq.n.ltoreq.1.7, 20, z>0 and y+z=4-n-x); and (C) a curing agent. The coating composition exhibits excellent storage stability after the curing agent is added, suppresses aggregation of fine silica particles in spray coating and provides coating films having a high hardness and exhibiting excellent weatherability, water resistance, chemical resistance and adhesion.
