ADHESIVE COMPOSITION AND OPTICAL MEMBER

摘要

An adhesive composition is provided to prevent the discoloration or bubbling under high relative humidity for a long-term and to ensure excellent heat resistance, light leakage and re-working property. An adhesive composition comprises a copolymer polymer (A1), and a copolymer polymer (A2) increasing the cross linkage of the polymer (A1) by adding a cross-linking agent. The copolymer polymer (A1) is (a1) acrylic acid ester or the methacrylic acid ester 70~98.9 weight%, and (a2) aceto acetyl group - containing monomer 1~20 weight% and (a3) a copolymer 0.1~10 weight% of acrylic acid ester and methacrylic acid ester to become a cross-linkage point.
