PURPOSE: To obtain a pressure-sensitive adhesive composition excellent in durability by mixing an acrylic resin with a curing agent, a silane compound represented by a specified formula and an epoxy alcohol. CONSTITUTION: A monomer (e.g. n-butyl acrylate) is copolymerized with a comonomer (e.g. acrylic acid) in the presence of a polymerization initiator in a solvent (e.g. toluene) to prepare an acrylic copolymer solution. This solution is mixed with 0.01-10 pts.wt., per 100 pts.wt. solid matter of the solution, curing agent comprising an isocyanate compound (e.g. tolylene diisocyanate), 0.0001-10 pts.wt. silane compound represented by formula I (R1 to R4 are each 1-24C alkyl or alkoxy) (e.g. tetramethoxysilane), 0.0001-10 pts.wt. epoxy alcohol represented by formula II (n is 1-20) (e.g.γ-glycidoxypropanol) and a curing aid comprising a polyol compound and/or a melamine compound to obtain a pressure-sensitive adhesive composition.
