CURABLE COMPOSITION, COMPOSITION FOR OPTICAL MATERIAL, OPTICAL MATERIAL, LIQUID-CRYSTAL DISPLAY, TRANSPARENT CONDUCTIVE FILM, AND PROCESS FOR PRODUCING THE SAME

Document Type and Number:

WIPO Patent Application WO/2001/081475

Kind Code:

A1

Abstract:

A curable composition which comprises the following components: (A) an aliphatic organic compound having, per molecule, at least two carbon-carbon double bonds reactive with an SiH group, (B) a compound having at least two SiH groups per molecule, and (C) a hydrosilylation catalyst. This curable composition is mixed beforehand to react the SiH-reactive carbon-carbon double bonds in the composition with part or all of the SiH groups to cure the composition, whereby an optical material can be obtained. Thus, a curable composition and an optical material having high heat resistance, low birefringence, a low photoelastic efficient, high optical transparency, and toughness can be provided. Also provided are a process for producing the material and a liquid-crystal display employing the optical material.
