ADHESIVE EXCELLENT IN REWORKABILITY AND ADHESIVE FILM

PROBLEM TO BE SOLVED: To provide an adhesive which shows a reworkability (reattachment property) when stuck onto a glass surface etc. and increases its adhesive force over time to exert a stronger and stabler adhesive force at completion of a manufacturing step or during a circulation stage, and an adhesive film using the same. SOLUTION: The adhesive is manufactured by adding 0.05-3.0 pts.mass silane coupling agent against 100 pts.wt. copolymer composition, wherein the copolymer composition is prepared through solution polymerization of 100 pts.mass mixed monomer component containing 37-83 pts.mass 3-8C alkyl (meth)acrylate, 7-20 pts.mass methyl acrylate, 10-30 pts.mass ethyl acrylate, 0.5-10 pts.mass carboxyl group-containing vinyl monomer and 0.05-3 pts.mass hydroxyl group-containing alkyl (meth)acrylate. The adhesive film excellent in reworkability is manufactured by applying this adhesive onto a substrate film. COPYRIGHT: (C)2006,JPO&NCIPI
