Curing agent, curable compositions, compositions for optical materials, optical materials, their production and liquid crystal displays and LED's made by using the materials
The invention aims at a curing agent, curable compositions or compositions for optical materials, capable of providing for cured artifacts having laudable heat resistance, optical transparency, and light resistance; optical materials and methods for their production; and liquid crystal displays and LED's made by using the materials. A curing agent, which comprises at least two SiH groups, is obtainable by subjecting an aliphatic organic compound (α1) and an acyclic and/or cyclic polyorganosiloxane (β1) to hydrosilylation reaction. The curing agent is also obtainable by subjecting an organic compound (α2) and a cyclic polyorganosiloxane (β2) to hydrosilylation reaction.
