<p>An adhesive composition consists essentially of a styrene-butadiene block copolymer of configuration A-B-A, a resinous aromatic tackifier, calcium carbonate and a solvent selected from aromatic hydrocarbons having from six to eight carbon atoms, aliphatic hydrocarbons having from six to eight carbon atoms and ketones having from two to four carbon atoms and a boiling point between 60.degree. and about 145.degree.C. The composition comprises, per 100 parts by weight of block copolymer, from 20-125 parts by weight of tackifier, from 60-500 parts by weight of calcium carbonate, and from 85-1500 parts by weight of solvent.</p> |
