【Task】 Provided is an aqueous silicone resin composition which is excellent in adhesion to a substrate, abrasion resistance and surface smoothness and is useful for surface coating of rubber materials and fiber materials. [Solution] (A) having a [R 1 2 SiO 2/2] units and [R 2 SiO 3/2] units, the molar ratio of the two units: [R 1 2 SiO 2/2] / [R 2 SiO 3 / 2 ] = 1 / (0-0.01) Organopolysiloxanes (B), (C) and (D) having terminal hydroxyl groups blocked, organotrialkoxysilanes containing amide bonds and carboxyl groups and epoxy groups containing carboxyl groups organotrialkoxysilane / or their partially hydrolyzed condensate (E) a curing catalyst (F) a silica / organo silsesquioxane surface of Sun-based fine particles are organo silylated with [R 5 3 SiO 1/2] units An aqueous silicone resin composition containing hydrophobic fine particles (G) spherical organic resin fine particles.
