The disclosure relates to a (meth)acrylate adhesive composition comprising a (meth)acrylate polymer, a cross-linking agent and a reactive siloxane copolymer with the acid value of the (meth)acrylate polymer is between 0 and 15 mgKOH/g, and the reactive siloxane copolymer derived from the copolymerization of a silane compound represented by the formula: X—R1—SiR23-a(OR3)a (I), a non-hydroxyl acrylate monomer containing C1-C4 alkyl group and a hydroxyl (meth)acrylate monomer, wherein the use amount of the reactive siloxane copolymer is between 0.1 parts to 6 parts by weight per hundred parts by weight of the (meth)acrylate polymer, wherein X is an acryl group or a (methyl)acryloxy group, R1 is a C1-C4 alkyl group or alkoxy group, R2 and R3 respectively are C1-C4 alkyl group, and a is an integer between 1 to 3. The present (meth)acrylate adhesive composition can provide an enhanced adhesion and weather resistance, also an enhanced stability over time and storage stability, when be used in polarizer bonding, can show a satisfied adhesion reliability and a proper rework ability.
