Abstract
A polymerizable composition that is suitable to produce a molded product that can suppress cracking and dimensional change caused by a high-temperature heat history with a high refractive index of a cured product maintained. A polymerizable composition including (a) 100 parts by mass of the specific reactive silsesquioxane compound, (b) 10 to 500 parts by mass of the specific fluorene compound, a cured product obtained by the polymerizable composition and a material for a high-refractive index resin lens including the polymerizable composition.
