CURABLE COMPOSITION

摘要

PURPOSE: A curable composition is provided to have excellent processability and workability, and high refractivity before and after curing, and not causing color change like whitening in high temperatures and high humidity condition. CONSTITUTION: A curable composition comprises a mixture of a linear polysiloxane compound and a siloxane oligomer compound, and a silicon compound comprising hydrogen atoms combined to silicon atoms. The linear polysiloxane comprises an alkenyl group combined to the silicon atoms, comprises siloxane units in chemical formula 1: R^aR^bSiO_2/2, and chemical formula 2: R^cR^dSiO_2/2. The number of moles of the siloxane unit in chemical formula 1 is 1-5 times than number of moles of the siloxane unit in chemical formula 2. The siloxane oligomer compound is in chemical formula 3.
