Claims53
A pressure sensitive adhesive composition comprising a rubber modified acrylic and/or vinyl resin comprising the mini-emulsion polymerization product of at least one rubber compound substantially dissolved in at least one acrylic and/or vinyl monomer, wherein said resin comprises a rubber portion derived from said rubber compound and an acrylic and/or vinyl portion derived from said acrylic and/or vinyl monomer, wherein said pressure sensitive adhesive composition exhibits a 50° C. hold power of at least 100 hours.
A pressure sensitive adhesive composition comprising water and a rubber modified acrylic and/or vinyl hybrid resin, wherein said rubber modified acrylic and/or vinyl hybrid resin comprises the mini-emulsion polymerization product of at least one rubber compound substantially dissolved in at least one acrylic monomer and/or vinyl monomer, wherein said pressure sensitive adhesive composition exhibits a 50° C. hold power of at least 100 hours.
A pressure sensitive adhesive composition comprising a rubber modified acrylic and/or vinyl resin comprising a rubber portion derived from at least one rubber compound and an acrylic and/or vinyl portion derived from at least one acrylic and/or vinyl monomer, wherein said resin has a glass transition temperature of about 20° C. or less determined by differential scanning calorimetry, wherein said pressure sensitive adhesive composition exhibits a 50° C. hold power of at least 100 hours.
