PROBLEM TO BE SOLVED: To provide an aqueous low fouling type coating composition capable of being used together with a coating material coated directly on concrete, mortar and various boards, and also used as a final finish-coating material for various finish-coating materials, a pattern-coating material, a stone tone-coating material, a design-coating material, etc. SOLUTION: This aqueous low fouling type coating composition contains 3-15 pts. mass anisotropic colloidal silica having a connected chain shape as a solid portion of SiO<SB>2</SB>based on 100 pts. mass(based on its solid portion) acrylic resin emulsion. The acrylic resin emulsion is prepared by adding at least 1 kind selected from a silane-based monomer, a silicate and a polycondensate of the silicate to an acrylic resin emulsion obtained by performing an emulsion polymerization of an acrylic monomer, for swelling the acrylic resin particles and performing a seed polymerization, etc. COPYRIGHT: (C)2004,JPO
