PURPOSE:To provide the titled adhesive composed of a styrene block copolymer resin and a styrene resin and having improved strength in hot state without lowering initial tackiness. CONSTITUTION:The objective composition can be produced by compounding (A) 100pts.(wt.) of a styrene block copolymer resin (e.g. styrene-butadiene block copolymer) with (B) preferably 20-60pts. of a styrene resin (preferably an alpha-methylstyrene resin or styrene/alpha-methylstyrene copolymer resin having a softening point of 130-160 deg.C).
