LIQUID ADHESIVE COMPOSITION, OPTICAL MEMBER IN WHICH THE COMPOSITION IS ENCAPSULATED, AND METHOD FOR MANUFACTURING THE OPTICAL MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a liquid adhesive composition which improves followability to the difference in level between a printing ink layer and the surface of a transparent substrate, has excellent reworkability, and can be adapted to sticking in a vacuum state.

SOLUTION: The liquid adhesive composition comprises: an energy ray-polymerizable urethane (meth)acrylate; an energy ray polymerization initiator; and a silicone oil having a crosslinkable substituent and a mass average molecular weight (Mw) of 400-5,000; wherein a viscosity at 25°C is 1,000-4,000 mPa s. In an optical member 1, the liquid adhesive composition 11 is encapsulated in a frame-shaped marginal part 14 disposed between a transparent front substrate 12 and a transparent conductive film 13.
