Title:
POLARIZATION PLATE
Document Type and Number:
WIPO Patent Application WO/2014/129260
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a polarization plate comprising a cation-polymerizable adhesive exhibiting superior curability even when using a protective film including a urethane primer layer. The present invention provides a polarization plate characterized in that a cation-polymerizable adhesive that contains a cation-polymerizable compound, a cationic-polymerization initiator, a thioxanthone compound, and a naphthalene compound is used to adhere a polarization element and a protective film including a urethane primer layer. The polarization plate of the present invention exhibits superior curability even when using a cation-polymerizable adhesive and a protective film including a urethane primer layer, and as such contributes to the further improvement of optical characteristics.
