Title:
OPTICAL MEMBERS AND ULTRAVIOLET CURABLE ADHESIVE USED IN MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2013/105163
Kind Code:
A1
Abstract:
The present invention pertains to an ultraviolet curable adhesive characterized by: being used to bond an optical substrate and an optical substrate having a light-blocking section to a surface; and containing an organic compound (A) that emits light by absorbing ultraviolet rays, and has a specific maximum absorption wavelength and a specific maximum emission wavelength, a photopolymerizable compound (B), and a photopolymerization initiator (C). The present invention further pertains to a hardened material obtained by exposing said adhesive to ultraviolet rays, and optical members, such as a touch panel, containing said hardened material. By using this ultraviolet curable adhesive, the adhesive, which is positioned in a light-blocking region that blocks light due to the existence of the light-blocking section, can be sufficiently cured by projecting ultraviolet rays from one direction without damaging a liquid crystal display device or the like, even if the light-blocking section has been formed on an optical substrate such as a transparent protective sheet.
