Document Type and Number:
WIPO Patent Application WO/2017/169838
Kind Code:
A1
Abstract:
[Problem] To provide an active energy ray-curable resin composition for an optical article, a cured body, and an optical sheet, which offer excellent shape reproducibility, scratch resistance, dimensional stability, and curling performance. [Solution] Provided is an active energy ray-curable composition for an optical article containing an active energy ray-polymerizable compound and a photopolymerization initiator, the composition (1) containing a polymerizable compound that has two or more active energy ray-polymerizable groups and an ethylene oxide group, the weight concentration of the ethylene oxide group being 6.0 to 15.0 wt% relative to the total amount of the active energy ray-polymerizable compound, and (2) containing 30 to 70 wt% of a polymerizable compound having two or more active energy ray-polymerizable groups, relative to the total amount of the active energy ray-polymerizable compound. Also provided are: a cured body obtained by curing, with active energy rays, the active energy ray-curable composition for an optical article; and an optical sheet.
