The present invention is directed to pressure-sensitive adhesive compositions and pressure-sensitive adhesive constructions fabricated using the pressure- sensitive adhesive compositions. The pressure-sensitive adhesive compositions comprise about 10 to about 40% of a styrene-isoprene block copolymer, about 5 to about 30% of a styrene-butadiene block copolymer, about 30 to about 65% of an aromatically modified tackifying resin, about 8 to about 30% of a plasticizing oil and optionally about 0.2 to about 2% of an antioxidant, wherein the percentages are based on the total weight of the composition.
La présente invention concerne des compositions d'adhésif autocollant et des constructions d'adhésif autocollant fabriquées en utilisant lesdites compositions d'adhésif autocollant. Ces compositions d'adhésif autocollant comprennent entre environ 10 et environ 40 % en poids d'un copolymère séquencé de styrène-isoprène, entre environ 5 et environ 30 % en poids d'un copolymère séquencé de styrène-butadiène, entre environ 30 et environ 65 % en poids d'une résine donnant du collant, à modification aromatique, entre environ 8 et environ 30 % en poids d'une huile plastifiante et éventuellement entre environ 0,2 et 2 % en poids d'un antioxydant, les pourcentages étant basés sur le poids total de la composition.
