Abstract
The present disclosure relates to a (meth)acrylate adhesive composition comprising a (meth)acrylated polymer, a crosslinking agent and a silane copolymer, wherein the silane copolymer comprises 70 to 95 weight parts of an acrylate monomer containing C-Calkyl group and 5 to 30 weight parts of a silane represented by the following formula (I):X—R—SiR(OR)  (I)wherein the weight-average molecular weight of the silane copolymer is ranging from 40,000 to 150,000. The silane copolymer can enhance the initial adhesion strength, rework ability and weather resistance of the (meth)acrylate adhesive composition. Furthermore, the (meth)acrylate adhesive composition can be used in the flexible optical film with a good bending restoring property and adhesion.
