Document Type and Number:
WIPO Patent Application WO/2019/093157
Kind Code:
A1
Abstract:
This ultraviolet-curable adhesive composition is a resin composition used for bonding at least two optical substrates together, said resin composition comprising a photopolymerizable oligomer (A) and a (meth)acrylate monomer (B). The weight ratio of component (A) and component (B) in the resin composition is within the range of 2/1-2/3. The weight-average molecular weight of the photopolymerizable oligomer (A) is within the range of 7000-100000, and a cured product of the resin composition has a light transmittance of at least 85% in the wavelength region of 450-800 nm.
