Pressure-sensitive adhesive compositions are disclosed which essentially comprise (I) a base block copolymer, (II) a resinous tackifier, (III) a selected naphthenic or paraffinic mineral oil and (IV) a selected aromatic synthetic oil. Tackiness, adhesion, cohesion and corrugated fiber board adhesiveness characteristics can be greatly improved by the addition of specified amounts of such mineral oil and aromatic oil as softeners.
