Title:
ACTIVE ENERGY RAY-CURABLE RESIN COMPOSITION FOR OPTICAL ARTICLES, CURED PRODUCT, AND OPTICAL SHEET
Document Type and Number:
WIPO Patent Application WO/2018/070256
Kind Code:
A1
Abstract:
Provided is an active energy ray-curable resin composition capable of forming an optical article which has a high refractive index and excellent scratch resistance, exhibits self-healing properties even when scratched, and has excellent adhesion under high temperature and high humidity conditions. This active energy ray-curable resin composition for optical articles contains a phenoxybenzyl acrylate and a fluorene-based (meth)acrylate having a long alkylene oxide chain. By using this active energy ray-curable resin composition, a prism sheet can be obtained which is capable of achieving a high refractive index and proper self-healing properties, while also exhibiting adhesion under high temperature and high humidity conditions, as well as scratch resistance.
