Beschreibung
Zusammenfassung:	1. A pressure sensitive adhesive composition comprising: (A) 92 to 99.9 parts of a block copolymer adhesive composition comprising: (a) a first block copolymer comprising (i) at least one rubbery block comprising a first polymerized conjugated diene, a hydrogenated derivative thereof, or combinations thereof; and (ii) at least one glassy block comprising a first polymerized monovinyl aromatic monomer; and (B) 0.1 to less than 8 parts of an acrylic adhesive composition comprising: (i) 70 to 100 parts of at least one acrylic or methacrylic ester of a non-tertiary alkyl alcohol, wherein the non-tertiary alkyl alcohol contains 4 to 20 carbon atoms; and (ii) 0 to 30 parts of a copolymerized reinforcing monomer.
