Zusammenfassung:	PURPOSE:To obtain a pressure-sensitive adhesive composition for kraft pressure- sensitive adhesive tape which has pressure-sensitive adhesive characteristics including excellent pressure-sensitive adhesiveness and heat resistance, a low viscosity and a high solid content, and therefore a good workability in coating and costs suitably. CONSTITUTION:The composition is a solvent-based pressure-sensitive adhesive composition containing a styrene/isoprene block copolymer and a natural rubber in a weight ratio of 0.2-1.5, the content of the styrene/isoprene block copolymer in the block copolymer being 50wt.% or below, and the content of the styrene/ isoprene/styrene block copolymer in the block copolymer being 50wt.% or above.
