14 Claims

1. A (meth)acrylate adhesive composition, comprising:

a (meth)acrylate polymer;

a crosslinking agent; and

a siloxane copolymer, wherein the siloxane copolymer comprising:

70 to 95 weight percent of the acrylic monomers containing C₁-C₄alkyl group; and

5 to 30 weight percent of the silane compound represented by the following formula (I):

X—R¹—SiR²_3-a(OR³)_a (I)

wherein X is an acrylic group or (meth)acrylic group, R¹is an C₁-C₈alkyl group or alkoxy group, R²and R³is an C₁-C₄alkyl group respectively, a is an integer of 1 to 3, and the weight-average molecular weight of the siloxane copolymer is ranging between 40,000 and 150,000;

wherein the usage amount of the siloxane copolymer is between 0.2 parts to 25 parts by weight per hundred parts by weight of the (meth)acrylate polymer.
