The present invention relates to pressure sensitive adhesive compositions prepared from novel anionic block copolymers of aromatic vinyl compounds and conjugated dienes. The block copolymers are a mixture of a high molecular weight linear and/or radial block copolymer component (SBC1 and/or SBC2), and a diblock copolymer component (D1). The block copolymer may be combined with other block copolymers, tackifying resins, oils and other components to form the adhesives of the present invention. The pressure sensitive adhesives of the present invention maintain their performance at elevated temperatures and fail cohesively making them particularly useful for die-cuttable label applications. The pressure sensitive adhesives compositions may also comprise ester plasticizers typically used for PVC and thus make adhesives particularly suitable for PVC film labels and decals.
