Title:
METHOD FOR PRODUCING OPTICAL MEMBER AND USE OF ULTRAVIOLET RAY CURED RESIN COMPOSITION FOR SAME
Document Type and Number:
WIPO Patent Application WO/2013/057958
Kind Code:
A1
Abstract:
The present invention pertains to: a method for producing an optical member resulting from pasting together at least two optical substrates, which are optical substrates having at least one light shielding section, using an ultraviolet ray cured resin composition containing a (meth)acrylate (A) and a photoinitiator (B), wherein the method has specific steps 1 to 3; an optical member obtained by means of the method for producing; a use of the ultraviolet ray cured resin composition that is for the method for producing and that contains a (meth)acrylate (A) and a photoinitiator (B); and the ultraviolet ray cured resin composition. By means of the method for producing, it is possible to produce a pasted-together optical member—for example a display body unit or a touch panel having an optical substrate having a light shielding section, or the like—such that damage to the optical substrates is low, production characteristics are favorable, and curing and adhesion are favorable, and it is possible to obtain an optical member having a high degree of curing of the resin at the light shielding section and high reliability.
