PURPOSE: To obtain a coating composition comprising a specific aminoalkylalkoxysilane compound, water, an organic solvent, an acid and functional fine particles, useful for forming a transparent coating film excellent in wear resistance, water repellency, stain resistance, weather resistance, antimicrobial resistance, etc. CONSTITUTION: This coating composition comprises (A) an aminoalkylalkoxysilane compound of the formula (Y is an amino group- containing organic group; Y<1> is a hydrocarbon group; R is a 1-5C alkyl; (m) is an integer of 1-5; (n) is an integer of 0-2) (especially preferablyγ- aminopropyltriethoxysilane), (B) water, (C) an organic solvent, (D) an acid (especially preferably methyl alcohol) and (E) functional fine particles (preferably fluororesin fine particles) and has pH6.5 to pH8.0. The blending ratio of the components is 0.5-300 pts.wt. of the component A, 0.5-300 pts.wt. of the component B, 0.5-300 pts.wt. of the component C and 0.3-30 pts.wt. of the component D based on 1 pt.wt. of the component A and the amount of the composition E is preferably 15-75wt.% based on the whole solid content.
