Abstract:
A polyurethane resin composition for optical applications can contain, as essential components, a polyisocyanate and a polyester-ether polyol obtained by polycondensation of a glycol component containing an alkylene oxide adduct of a bisphenol and an aromatic carboxylic acid component and particularly preferably having a glass transition temperature of 50° C. or lower. An optical material using the composition is also provided for.
