PROBLEM TO BE SOLVED: To provide an adhesive composition having high adhesiveness over a wide range of temperature, by using a base resin comprising a thermoplastic, an ester type urethane resin having a glass transition temperature in a specific range, an acrylic resin and a polystyrene resin having a glass transition temperature in a specific range. SOLUTION: This adhesive composition comprises a thermoplastic base resin comprising 80 to 98 pts.wt. of an ester type urethane resin having hot melt properties and having a glass transition temperature in a range of 25 to 40 deg.C and 2 to 20 pts.wt. of an acrylic resin or a polystyrene resin having a glass transition temperature in a range of 40 to 65 deg.C. The composition may further be compounded, if desired, with a bromine-based flame retardant and a chlorine- based flame retardant in an amount of 20 to 60 pts.wt. in total, relative to 100 pts.wt. of the base resin, a hydrophobic silica having a particle size of 0.01 to 10μm in an amount of 5 to 10 pts.wt., and a talc and/or clay having a particle size of 0.1 to 10μm in an amount of 5 to 50 pts.wt. |
