Abstract
A hydrosilylation reaction curable composition including a silsesquioxane polymer, a cross-linking compound, a hydrosilylation reaction catalyst and colloidal silica having a surface coating formed thereon. The curable composition is cured to form a cured resin having high fracture toughness and strength without the loss of elastic modulus and glass transition temperature.
