NOVELTY - An aqueous curable resin composition comprises resin particles containing UV absorber included in composite resin (ABC), dispersed in an aqueous medium. Resin (ABC) formed by chemically bonding polysiloxane segment (B) of composite resin (AB) consisting of polymer segment (A) having neutralized acidic radical, and polysiloxane segment (B), with polysiloxane segment (C) derived from condensate of trialkoxysilane having 1-3C alkyl group coupled through silicon-oxygen bond. Resin (ABC) is dissolved or dispersed in aqueous medium.    USE - Aqueous curable resin composition is used for coating materials of various base materials e.g. metals, glass, paper, timber, plastic base material, etc. of solar cells. Can also be used for mobile telephones, domestic electrical appliances, automotive interior/exterior materials, inorganic building materials, and electronic office equipment.    ADVANTAGE - The aqueous curable resin composition forms cured coating films having excellent base-material surface-protection property, contamination resistance, weather resistance, crack resistance, and UV-shielding property.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of aqueous curable resin composition, which involves obtaining an organic solvent solution of vinyl polymer (a2) by polymerizing a vinyl monomer containing hydrolyzable-silyl-group-containing vinyl monomer and silanol-group-containing vinyl monomer under organic solvent, obtaining organic solvent solution of resin (C) containing polysiloxane coupled with vinyl polymer by reacting vinyl polymer (a2) and a silane compound under organic solvent solution of polymer (a2), neutralizing the hydrophilic group after production of organic solvent solution of polymer (a2) or organic solvent solution of resin (C), dissolving or dispersing the neutralized material in aqueous medium, adding a UV absorber to the resin solution, and mixing the organic solvent solution and water-containing neutralized material.
