Document Type and Number:
WIPO Patent Application WO/2020/194886
Kind Code:
A1
Abstract:
[Problem] To provide: a curable composition capable of forming cured objects which have excellent adhesion to the substrates and have high total light transmittance and a satisfactorily reduced haze; and a cured object obtained from the curable composition. [Solution] A curable composition which comprises (A) a urethane (meth)acrylate, (B) a thiocarboxylic acid derivative, (C) triallyl isocyanurate, and (D) a photopolymerization initiator, wherein the thiocarboxylic acid derivative (B) is contained in an amount of 50 parts by mass or more per 100 parts by mass of the urethane (meth)acrylate (A) and the triallyl isocyanurate (C) is contained in an amount of 40 parts by mass or more per 100 parts by mass of the urethane (meth)acrylate (A); and a cured object formed from the curable composition.
