Abstract
Pressure-sensitive adhesives are prepared from (meth)acrylate esters of 2-alkyl alkanols. The adhesives are characterized by exhibiting an overall balance of adhesive and cohesive characteristics and exceptional adhesion to low surface energy substrates.
Claims19
A pressure-sensitive adhesive composition comprising (co)polymers of a) (meth)acrylate ester of 2-alkyl alkanols wherein the molar carbon number average of said 2-alkyl alkanols is 12 to 32;
- and optionally b) (meth)acrylate esters of C1-12 alkanols;
- wherein the molar carbon number average of the alkanols of the a) and b) (meth)acrylic acid esters is 12 to 32.
