Patent ID: 8551616

Claim:
An adhesive composition comprising: a) a block copolymer comprising at least two A endblock polymeric units that are each derived from a first monoethylenically unsaturated monomer comprising a methacrylate, styrene, or combination thereof, wherein each A endblock has a glass transition temperature of at least 50° C.; and at least one B midblock polymeric unit that is derived from a second monoethylenically unsaturated monomer comprising a (meth)acrylate, vinyl ester, or combination thereof, wherein each B midblock has a glass transition temperature no greater than 20° C.; and b) a tackifier mixture comprising 1) a first solid tackifier having a glass transition temperature greater than or equal to 20° C. and comprising at least 70 weight percent of a first rosin acid, first rosin ester, or mixture thereof having zero or one carbon-carbon double bond; 2) a second solid tackifier having a glass transition temperature greater than or equal to 20° C. and comprising no greater than 50 weight percent of the first rosin acid, first rosin ester, or mixture thereof having zero or one carbon-carbon double bond; and 3) a liquid tackifier having a glass transition temperature less than or equal to 0° C., wherein the liquid tackifier comprises a rosin acid, a rosin ester, or a mixture thereof.
