High performance water-based tackified acrylic pressure sensitive adhesives

An article of manufacture comprising:

• a support member and a pressure-sensitive adhesion layer attached thereto comprising a) about 59 weight % to about 98.5 weight %, based on the total weight of the adhesive of a first polymer that comprises a majority component of either 2-ethylhexylacrylate or butyl acrylate copolymerized with a minority component of either methyl methacrylate, vinyl acetate, or styrene, wherein the main component is present in the copolymer in relative proportion greater than the minor component;
• b) about 1 weight % to about 17.5 weight % based on the total weight of the adhesive of a second polymer consisting of an ethylene-acrylic acid copolymer having a number average molecular weight between 1500 and 3000 in combination with an oxidized polyethylene having a number average molecular weight between 800 and 6000;
• and c) about 0.5 weight % to about 40 weight % based on the total weight of the adhesive of a tackifier resin having a number average molecular weight between about 270 and about 1400, selected from the group consisting of rosin ester resin, rosin acid resin, synthetic hydrocarbon resin, synthetic terpenic resin and combinations of two or more thereof;
• wherein the adhesion layer is water-based and adapted for pressure-sensitive adhesion to substrates.
