Title:
OPTICAL MEMBER, AND ULTRAVIOLET-CURABLE ADHESIVE USED IN PRODUCTION OF SAME
Document Type and Number:
WIPO Patent Application WO/2013/105162
Kind Code:
A1
Abstract:
The present invention pertains to: an ultraviolet-curable adhesive that is used for bonding an optical substrate and an optical substrate having a light-blocking section on the surface thereof to one another, and is characterized by containing a compound (A) for absorbing ultraviolet rays and emitting light, a photopolymerizable compound (B), and a photopolymerization initiator (C); a cured product obtained by irradiating the adhesive with ultraviolet rays; and an optical member such as a touch panel which has the cured product. Using this ultraviolet-curable adhesive makes it possible to sufficiently cure an adhesive placed in a light-blocked region in which light is blocked by the presence of the light-blocking section, by irradiating with ultraviolet rays from one direction, without damaging a liquid crystal display device or the like, even when a light-blocking section is formed on an optical substrate such as a transparent protective sheet.
