PRESSURE-SENSITIVE ADHESIVE COMPOSITION, AND OPTICAL MEMBER USING THE SAME

PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive composition improved in light leakage by using a thermosetting interpenetrating polymer and being excellent in durability and peel strength by a blend effect of polymers instead of low molecular weight ones.SOLUTION: The pressure-sensiti...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive composition improved in light leakage by using a thermosetting interpenetrating polymer and being excellent in durability and peel strength by a blend effect of polymers instead of low molecular weight ones.SOLUTION: The pressure-sensitive adhesive composition is 8×10to 1×10dyne/cmin storage modulus and 83-95% in gel fraction shown by formula 1: Gel fraction (%)=(A/B)×100, wherein A is the mass remaining after dissolving the pressure-sensitive adhesive composition for 48 hours at normal temperature (23°C) in a solvent and drying for 24 hours and B is initial mass of the pressure-sensitive adhesive.
